Subject [jira] Commented: (HIVE-1064) NPE when operating HiveCLI in distributed mode
Date Wed, 20 Jan 2010 05:55:56 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1064?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12802685#action_12802685
] 

Ning Zhang commented on HIVE-1064:
----------------------------------

Carl, there are a lot of conflicts when applying this patch to the latest trunk. It may be
because of the two large patches committed recently. There should not be further large patches
in recently, can you  resolve the conflicts and resubmit a new patch? I'll start reviewing
right away from there.
