Subject [jira] [Updated] (HIVE-5214) Dynamic partitions/insert overwrite don't inherit groupname from table's directory
Date Wed, 04 Sep 2013 19:40:51 GMT

     [ https://issues.apache.org/jira/browse/HIVE-5214?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Thiruvel Thirumoolan updated HIVE-5214:
---------------------------------------

    Description: 
When dynamic partitions are created or insert overwrite without partitions, the files/partition-dirs
don't inherit the group name.

The query (say, insert overwrite table select *) uses the scratch directory for creating the
temporary data. The temporary data's perm/group is inherited from scratch directory. Finally,
the MoveTask does a rename of the temporary dir/files to be the target directory and an explicit
group/perm change does not happen.

HIVE-3756 fixed it for Load data, dynamic partitions/inserts have to be handled.
