Subject [jira] Commented: (HADOOP-5785) The job setup and cleanup tasks should be optional
Date Tue, 26 May 2009 11:45:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712973#action_12712973

Amareshwari Sriramadasu commented on HADOOP-5785:

bq. Also, instead of configuration, as JobSetup and JobCleanup are specified via the job's
OutPutCommitter, why not have something in the lines of the following and use them generically
to determine if a job needs setup/cleanup.
This cannot be done, because it is again user code. and we don't want to run any user code
in JobTracker.

> 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.
