配置Executor Server

Azkaban Executor Server 主要负责工作流程的提交、执行、检索和更新当前正在执行计划的数据，处理执行计划的日志。

1. 编辑azkaban.properties

xxxxxxxxxx
[root@node2 ~]# cd /opt/azkaban/azkaban-exec
[root@node2 azkaban-exec]# ls
bin  conf  lib  plugins
[root@node2 azkaban-exec]# vim conf/azkaban.properties

修改如下属性：

xxxxxxxxxx
default.timezone.id=Asia/Shanghai
azkaban.webserver.url=http://node2:8081
mysql.host=node1
mysql.password=123456
executor.port=12345

2. azkaban-exec/plugins/jobtypes/commonprivate.properties

添加如下配置：

xxxxxxxxxx
memCheck.enabled=false

否则容易出现：Cannot request memory (Xms 0 kb, Xmx 0 kb) from system for job

3. 同步 azkaban-exec 到所有node1、node3节点

xxxxxxxxxx
[root@node2 azkaban]# scp -r azkaban-exec node1:`pwd`
[root@node2 azkaban]# scp -r azkaban-exec node3:`pwd`

4. 启动exec server

xxxxxxxxxx
[root@node1 azkaban-exec]# bin/start-exec.sh
[root@node2 azkaban-exec]# bin/start-exec.sh
[root@node3 azkaban-exec]# bin/start-exec.sh

扩展：关闭命令bin/shutdown-exec.sh

5. 激活Executor
6. http://node1:12345/executor?action=activate
7. http://node2:12345/executor?action=activate
8. http://node3:12345/executor?action=activate

xxxxxxxxxx
```html
{"status":"success"} #表示登录成功
```

【温馨提示】重启Azkaban Executor Server得重新激活
