Subject [jira] Commented: (HADOOP-649) Jobs without any map and reduce operations seems to be lost after their execution
Date Tue, 13 Feb 2007 19:02:06 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12472828
] 

Doug Cutting commented on HADOOP-649:
-------------------------------------

This looks good to me.  It would be best to have a unit test, to make sure that it really
fixes the issue and that we don't break it again in the future.  Thomas, are you willing to
write one?

Also, please don't include the bug number in the patch itself.  We don't want the code to
get cluttered with comments documenting its history: we leave history to subversion.

Thanks!

> When a job does not provide any file splits (because there is no data present), the job
successes but then it is lost by the job tracker. Is this normal ?
