在Oozie的Shell动作中执行Hive查询

Question

Is it possible to execute a hive query ( a query, that returns a value and it is used in the script) inside a shell script action in Oozie. The hive query is executed using hive -e option. What configurations need to be made in the workflow, if it can be done ?

Thanks..

Answer 1

Your shell action configuration could look like this:

  <action name="someaction">
    <shell xmlns="uri:oozie:shell-action:0.2">
      <job-tracker>${jobTracker}</job-tracker>
      <name-node>${nameNode}</name-node>
      <exec>somescript.sh</exec>
      <env-var>SOME_VARIABLE=1</env-var>
      <file>${someactionScriptPathName}#somescript.sh</file>
      <capture-output/>
    </shell>
    <ok to="nextaction"/>
    <error to="Kill"/>
  </action>

Your hive command can be now inside of the somescript.sh script.

I am also facing the same challenge by doing some analysis i came to conclusion that Oozie shell action is not meant to execute the hive scripts or queries but still i would like to understand where to add the parameter(oozie.action.sharelib.for.shell=hive) given by @younghobbit https://stackoverflow.com/users/2254048/younghobbit . Unfortunately the other comment and answer did not worked for me as its says the basic requirement by shell action.
