Oozie與Coordinator調度講解及系統時區配置與定時觸發兩種配置方式

1：修改本地linux時區

  查看時區

   - 號代表西  + 號 代表東 北京時間是東八區

    設置時區的配置文件所在位置

cd /usr/share/zoneinfo/

    選擇以亞洲的上海 的時區為基址

    刪除本地配置文件

rm -r /etc/localtime 

    創建一個硬連接

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

   時區變成東八區了

   設置時間

2：設置oozie的時區   在oozie-site.xml修改  oozie默認使用UTC 等同於GMT 服務器上是CST  要設置成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>

 

 

 

 

 

上面設置只是設置oozie調度的時間   oozie的web控制台時間也需要改

修改 oozie-console.js

在179行  getTimeZone

 

 啟動之前要先清除緩存

3：拷貝模板

4：修改job.properties

<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>

                </property>
            </configuration>
        </workflow>
    </action>
</coordinator-app>

 6.把文件上傳至hdfs

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

 

 7：啟動運行
