Oozie与Coordinator调度讲解及系统时区配置与定时触发两种配置方式

1：修改本地linux时区

查看时区

- 号代表西  + 号 代表东 北京时间是东八区

设置时区的配置文件所在位置

 cd /usr/share/zoneinfo/

选择以亚洲的上海 的时区为基址

删除本地配置文件

 rm -r /etc/localtime 

创建一个硬连接

  ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

时区变成东八区了

设置时间

2：设置oozie的时区   在oozie-site.xml修改  oozie默认使用UTC 等同于GMT 服务器上是CST  要设置成GMT+0800

  <!-- Time Zone -->
  <property>
      <name>oozie.processing.timezone</name>
      <value>GMT+0800</value>
   </property>

  <property>
      <name>oozie.service.coord.check.maximum.frequency</name>
      <value>false</value>
   </property>

上面设置只是设置oozie调度的时间   oozie的web控制台时间也需要改

修改 oozie-console.js

在179行  getTimeZone

启动之前要先清除缓存

3：拷贝模板

4：修改job.properties

 oozie.coord.application.path=${nameNode}/${oozieAppsRoot}/cron-schedule

 <coordinator-app name="cron-coord" frequency="${coord:minutes(1)}"
                 start="${start}" end="${end}" timezone="GMT+0800"
                 xmlns="uri:oozie:coordinator:0.4">
         <action>
         <workflow>
             <app-path>${workflowAppUri}</app-path>
             <configuration>
                 <property>
                     <name>jobTracker</name>
                     <value>${jobTracker}</value>

                     <name>queueName</name>
                     <value>${queueName}</value>
                 </property>
             </configuration>
         </workflow>
     </action>
 </coordinator-app>

6.把文件上传至hdfs

 bin/hdfs dfs -put /opt/cdh-5.3.6/oozie-4.0.0-cdh5.3.6/oozie-apps/cron-schedule oozie-apps/

7：启动运行
