Oozie-自訂實現WorkFlow中shell action

標籤：cat   user   att   alt   exec   .sh   last   ble   exe   

1. 拷貝預設的shell目錄來進行修改

   $ cp -r ./examples/apps/shell/ my-apps/

2. 定義job.properties

   nameNode=hdfs://bigdata-00:8020jobTracker=bigdata-00:8032queueName=defaultexamplesRoot=user/wulei/my-apps/shell#定義workflow.xml路勁oozie.wf.application.path=${nameNode}/${examplesRoot}/workflow.xml#定義一個變數名儲存shell檔案名稱EXEC=oozie.sh

3. 定義workflow.properties

   <workflow-app xmlns="uri:oozie:workflow:0.4" name="shell-wf"> <start to="shell-node"/> <action name="shell-node">     <shell xmlns="uri:oozie:shell-action:0.2">         <job-tracker>${jobTracker}</job-tracker>         <name-node>${nameNode}</name-node>         <configuration>             <property>                 <name>mapred.job.queue.name</name>                 <value>${queueName}</value>             </property>         </configuration>         <exec>${EXEC}</exec>         <!-- 定義shell指令碼路勁 -->         <file>${nameNode}/${examplesRoot}/${EXEC}#${EXEC}</file> <!--Copy the executable to compute node‘s current working directory -->     </shell>     <ok to="end"/>     <error to="fail"/> </action> <kill name="fail">     <message>Shell action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message> </kill> <end name="end"/></workflow-app>

4. 定義要實現的指令碼
