[jira] Commented: (HADOOP-5785) The job setup and cleanup tasks should be optional

    [ https://issues.apache.org/jira/browse/HADOOP-5785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12711092#action_12711092 ] 

Amareshwari Sriramadasu commented on HADOOP-5785:
-------------------------------------------------

Should we have a configuration property to speficy whether job setup and job cleanup are needed or not?

If the configuration is set, there will be no user code executed. JIP will create temporary output directory in initTasks() and delete the same in garbageCollect() (same code as pre-3150).  Thoughts?

Should the configuration be job-level or cluster-level?
