             Summary: Insert overwrite local directory should perserve the 
overwritten directory permission
                 Key: HIVE-12965
                 URL: https://issues.apache.org/jira/browse/HIVE-12965
             Project: Hive
          Issue Type: Bug
            Reporter: Chaoyu Tang
            Assignee: Chaoyu Tang


In Hive, "insert overwrite local directory" first deletes the overwritten 
directory if exists, recreate a new one, then copy the files from src directory 
to the new local directory. This process sometimes changes the permissions of 
the to-be-overwritten local directory, therefore causing some applications no 
more to be able to access its content.
