Subject [jira] Created: (HIVE-1944) dynamic partition insert creating different directories for the same partition during merge
Date Wed, 02 Feb 2011 06:59:28 GMT
dynamic partition insert creating different directories for the same partition during merge
-------------------------------------------------------------------------------------------

                 Key: HIVE-1944
                 URL: https://issues.apache.org/jira/browse/HIVE-1944
             Project: Hive
          Issue Type: Bug
            Reporter: Ning Zhang
            Assignee: Ning Zhang


If dynamic partition insert generates multiple partitions and some partitions need to be merge
(MR task) and some need not (move task), parallel execution could cause the move task finish
first and created the partition directory (say ds=1) first. When the MR job finished, it created
a different directory (ds=1_1) for the same partition ds=1.
