Pengcheng Xiong commented on HIVE-16189:
----------------------------------------

I saw your point. Thanks for the detailed explain in RB. And the test case proved this. Just
one more point, could u add another test case which includes an encrypted partitioned table
renaming but failed? Thanks.

> 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.
