Subject [jira] Commented: (HADOOP-5785) The job setup and cleanup tasks should be optional
Date Tue, 26 May 2009 14:17:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12713018#action_12713018
] 

Vinod K V commented on HADOOP-5785:
-----------------------------------

bq. This cannot be done, because it is again user code. and we don't want to run any user
code in JobTracker.
If not a method, it can be a simple protected boolean OutputCommitter.isJobSetupNeeded over-ridable
by subclasses. Does that work?

> For jobs that require low latency and do not require setup or cleanup tasks for the job,
it should be possible to turn them off for that job.
