Subject [jira] Commented: (HIVE-1582) merge mapfiles task behaves incorrectly for 'inserting overwrite directory...'
Date Mon, 23 Aug 2010 03:25:16 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1582?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12901250#action_12901250
] 

Ning Zhang commented on HIVE-1582:
----------------------------------

I'm confused. Do you mean the second job should not be started or the second job should not
be filtered out? I've tested the behaviors before and after HIVE-1307, and they are the same
and always fires the merge job.
