Subject [jira] [Commented] (HIVE-7273) Hive job fails due to unable to rename reducer output file
Date Mon, 23 Jun 2014 09:01:41 GMT

    [ https://issues.apache.org/jira/browse/HIVE-7273?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14040537#comment-14040537
] 

Navis commented on HIVE-7273:
-----------------------------

The directory is expected to be created in ExecDriver before job submitting. Could you provide
a query which can reproduce the situation? Fail of other tasks in the query also can make
exceptions like above.
