赫拉(hera)分布式任务调度系统之Q&A(五)

前言

在大数据平台,随着业务发展,每天承载着成千上万的ETL任务调度,这些任务集中在hive,shell脚本调度。怎么样让大量的ETL任务准确的完成调度而不出现问题,甚至在任务调度执行中出现错误的情况下,任务能够完成自我恢复甚至执行错误告警与完整的日志查询。hera任务调度系统就是在这种背景下衍生的一款分布式调度系统。随着hera集群动态扩展,可以承载成千上万的任务调度。它是一款原生的分布式任务调度,可以快速的添加部署wokrer节点,动态扩展集群规模。支持shell,hive,spark脚本调度,可以动态的扩展支持python等服务器端脚本调度。

hera分布式任务调度系统是根据前阿里开源调度系统(zeus)进行的二次开发,其中zeus大概在2014年开源,开源后却并未进行维护。我公司(二维火)2015年引进了zeus任务调度系统,一直使用至今年11月份,在我们部门乃至整个公司发挥着不可替代的作用。在我使用zeus的这一年多,不得不承认它的强大,只要集群规模于配置适度,他可以承担数万乃至十万甚至更高的数量级的任务调度。但是由于zeus代码是未维护的,前端更是使用GWT技术,难于在zeus上面进行维护。我与另外一个小伙伴(花名:凌霄,现在阿里淘宝部门)于今年三月份开始重写zeus,改名赫拉(hera)

***项目地址:git@github.com:scxwhite/hera.git ***

架构

hera系统只是负责调度以及辅助的系统,具体的计算还是要落在hadoop、hive、yarn、spark等集群中去。所以此时又一个硬性要求,如果要执行hadoop,hive,spark等任务,我们的hera系统的worker一定要部署在这些集群某些机器之上。如果仅仅是shell,那么也至少需要linux系统。对于windows系统,可以把自己作为master进行调试。

在这里插入图片描述

hera系统本身严格的遵从主从架构模式,由主节点充当着任务调度触发与任务分发器,从节点作为具体的任务执行器.架构图如下:

在这里插入图片描述 hera2.4 版本以上也支持了emr 集群,即允许任务执行在阿里云、亚马逊的 emr 机器之上,架构图如下: 在这里插入图片描述

安装部署与启动

创建表

当使用githera克隆到本地之后,首先在hera/hera-admin/resources目录下找到hera.sql文件,在自己的数据库中新建这些必要的表,并插入初始化的数据(如果你目前使用的是低版本的hera,那么你可以到 update 目录查看是否有你的 hera 版本升级的 ddl ,如果有请根据你的版本依次执行 ddl 语句)

此时可以在hera/hera-admin/resources目录下找到application.yml文件。在文件里修改数据源hera的数据源(修改druid.datasource下的配置)即可进行下面的操作。

## 省略部分
druid:
  datasource:
    username: root  #数据库用户名
    password: moye      #数据库密码
    driver-class-name: com.mysql.jdbc.Driver  #数据库驱动
    url: jdbc:mysql://localhost:3306/hera?characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&autoReconnect=true&allowMultiQueries=true
## 省略部分

打包部署

2.4.1及以上版本部署方案

[注:2.4.1及以上版本已经集成启动和关闭的sh]

在这里插入图片描述

如果你的 hera 使用的是 2.4.1 版本以上的,使用maven执行 mvn clean package -Dmaven.test.skip=true -Pdev 打包后在根目录会出现如图所示的压缩包 在这里插入图片描述

你可以通过 ssh 把该包上传到服务器,解压该tar.gz包。然后修改 config 目录下的application.yml 配置文件,在 bin 目录里执行 start.sh 脚本即可成功启动hera

2.4.1以下版本部署方案

mvn clean package -Dmaven.test.skip=true -Pdev

打包后可以进入hera-admin/target目录下查看打包后的hera-dev.jar 。此时可以简单使用java -server -Xms4G -Xmx4G -Xmn2G -jar hera.jar 启动项目,此时即可在浏览器中输入

localhost:8080/hera/login/admin

即进入登录界面,账号为hera 密码为biadmin,点击登录即进入系统。

注:目前hera有用户账户和组账户之分,默认跳转的登录地址为用户账户,需要用户注册(用户需要归属于一个组账户),然后hera组账户在用户管理里页面审核通过后即可登录用户账户。

顺便附上我的启动脚本

#!/bin/sh

JAVA_OPTS="-server -Xms4G -Xmx4G -Xmn2G -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -XX:CMSFullGCsBeforeCompaction=5 -XX:+CMSParallelInitialMarkEnabled -XX:CMSInitiatingOccupancyFraction=80  -verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -Xloggc:/opt/logs/spring-boot/gc.log -XX:MetaspaceSize=128m -XX:+UseCMSCompactAtFullCollection -XX:MaxMetaspaceSize=128m -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/opt/logs/spring-boot/dump"

log_dir="/opt/logs/spring-boot"
log_file="/opt/logs/spring-boot/all.log"
jar_file="/opt/app/spring-boot/hera.jar"


#日志文件夹不存在,则创建
if [ ! -d "${log_dir}" ]; then
    echo "创建日志目录:${log_dir}"
    mkdir -p "${log_dir}"
    echo "创建日志目录完成:${log_dir}"
fi


#父目录下jar文件存在
if [ -f "${jar_file}" ]; then
    #启动jar包 错误输出的error 标准输出的log
    nohup java $JAVA_OPTS -jar ${jar_file} 1>"${log_file}" 2>"${log_dir}"/error.log &
    echo "启动完成"
    exit 0
else
    echo -e "\033[31m${jar_file}文件不存在!\033[0m"
    exit 1
fi

关闭的脚本

#!/bin/bash
pid=`ps aux| grep java | grep hera | awk '{print $2}'`

[ ! $pid ] && echo "找不到hera的进程,请确认hera已经启动" && exit 0

res=`kill -9 $pid`

echo 关闭hera成功,pid:$pid

测试

默认登陆地址为:http://localhost:8080/hera 下面需要做的是在worker管理这里添加执行任务的机器IP,然后选择一个机器组(组的概念:对于不同的worker而言环境可能不同,可能有的用来执行spark任务,有的用来执行hadoop任务,有的只是开发等等。当创建任务的时候根据任务类型选择一个组,要执行任务的时候会发送到相应的组的机器上执行任务)。 对于执行work的机器ip调试时可以是master,生产环境建议不要让master执行任务。如果要执行map-reduce或者spark任务,要保证你的work具有这些集群的客户端。 那么我们就在work管理页面增加要执行的work地址以及机器组。

在这里插入图片描述

此时有30分钟的缓冲时间,master 才会检测到该 work 加入。为了测试,此时我们可以通过重启 master 来立刻使该 work加入执行组(后面会增加一键刷新work` 信息)。

此时要注意,我们的 work 也一定也要安装 hera 应用并启动。

重启后我们可以进入调度中心 ,在搜索栏里搜索 1 ,然后按回车 在这里插入图片描述

会发现一个 echoTest 任务 ,此时我们还不能执行任务,因为我们的所有任务的执行者登录用户。比如此刻我使用 hera 登录的,那么此时一定要保证你的 work 机器上有 hera 这个用户。 否则执行任务会出现 sudo: unknown user: hera 异常。 在这里插入图片描述

此时可以向我们填写的 work 机器上增加 hera 用户。

useradd hera

如果是 mac 系统 那么可以使用以下命令创建 hera 用户

sudo  dscl . -create /Users/hera
sudo  dscl . -create /Users/hera UserShell /bin/bash
sudo  dscl . -create /Users/hera RealName "hera分布式任务调度"
sudo  dscl . -create /Users/hera UniqueID "1024"
sudo  dscl . -create /Users/hera PrimaryGroupID 80
sudo  dscl . -create /Users/hera NFSHomeDirectory /Users/hera

此时点击手动执行->选择版本->执行。此时该任务会运行,点击右上角的查看日志,可以看到任务的执行记录。

此时如果任务执行失败,error 日志内容为

sudo: no tty present and no askpass program specified

那么此时要使你启动 hera 项目的用户具有 sudo -u hera 的权限(无须输入root密码,即可执行 sudo -u hera echo 1 ,具体可以在 sudo visudo 中配置)。 比如我启动 hera 应用的用户是 wyr 那么首先在终端执行 sudo visudo命令,此时会进入文本编辑 然后在后面追加一行

wyr             ALL=(ALL) NOPASSWD:ALL

如下图: 在这里插入图片描述 这样就会在切换用户的时候无须输入密码。当然如果你使用的是root用户启动,即可跳过这段。

由于在 hera 中还用到了 dos2unix ,需要在执行任务的work上安装 dos2unix 工具。

yum install dos2unix

如果一切配置完成,那么即可看到输出任务执行成功的日志。

在这里插入图片描述 至此 已经完成了 任务的手动执行。

TIPS

当然在部署的时候可能会出现各种状况。 比如:work 无法连接到 master,连接时抛出

java.net.NoRouteToHostException: 没有到主机的路由

这个时候请注意,我们的master使用的端口是:9887。需要在每台 hera 机器上的防火墙开启此端口(最好关闭防火墙 sudo service iptables stop )。

还有一种情况: work 可以连接上 master ,但是在master日志中发现 work 总是一段时间后断开。原因是:hera 各个机器的时间不一致,修改一下

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. {description} Copyright (C) {year} {fullname} This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. {signature of Ty Coon}, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.
