Wei Zheng commented on HIVE-15142:
----------------------------------
What I did is as follows:
1. Create a table with my user 'wzheng'
2. Find the table directory
3. chown the directory to another user 'test'
4. Manually trigger a compaction with user 'wzheng', then I can see the
backtrace abvove
I think that's equivalent to the scenario of doAs, where 'hive' doesn't own the
table but tries to compact it.
