协调者

<coordinator-app name="sampleCoord" frequency="${frequency}" start="${starttime}" end="${endtime}" timezone="${timezone}" xmlns="uri:oozie:coordinator:0.4">
<action>
<workflow>
<app-path>${workflowpath}</app-path>
</workflow>
</action>
</coordinator-app>

父工作流

<workflow-app xmlns = "uri:oozie:workflow:0.4" name = "Parent-Workflow">
<start to = "workflowAction1" />
<action name = "workflowAction1">
<sub-workflow>
<app-path>/user/user1/oozie-workflow/subWorkflow1.xml</app-path>
</sub-workflow>
<ok to = "end" />
<error to = "end" />
</action>

子工作流

<workflow-app xmlns = "uri:oozie:workflow:0.4" name = "subWorkflow">
<start to = "subWorkflowAction1" />
<action name = "subWorkflowAction1">
<hive xmlns = "uri:oozie:hive-action:0.4">
<job-tracker>${jobtracker}</job-tracker>
<script>${scriptpath}/dropTempTable.hive</script>
<param>Temp_TableVar=${concat(concat("HBASE_",replaceAll(wf:id(),"-    ","_")),"_TEMP")}</param>
</hive>
<ok to = "end" />
<error to = "kill_job" />
</action>

<kill name = "kill_job">
<message>Job failed</message>
</kill>
<end name = "end" />
</workflow-app>

在父工作流 xml 文件中添加传播配置标记解决了该问题。

<workflow-app xmlns = "uri:oozie:workflow:0.4" name = "Parent-Workflow">
<start to = "workflowAction1" />
<action name = "workflowAction1">
<sub-workflow>
<app-path>/user/user1/oozie-workflow/subWorkflow1.xml</app-path>
<propagate-configuration />
</sub-workflow>
<ok to = "end" />
<error to = "end" />
