Review request for hive.
Bugs: HIVE-16189
https://issues.apache.org/jira/browse/HIVE-16189
Repository: hive-git
Description
-------
If the table rename does not succeed due to its failure in moving the data to
the new renamed table folder, the changes in TAB_COL_STATS are not rolled back
which leads to invalid column stats.
This patch changes the order of metadata update and data move in alter table
rename operation, which makes it easier to roll back metadata changes when
moving data fails in rename a table.
