Sergey Shelukhin commented on HIVE-14969:
-----------------------------------------

[~wzheng] [~alangates] [~ekoifman] fyi.
We have discussed CTAS on IM.
Then, all the code involving directories is held together by duct tape and 
finger-crossing, so it would be worthwhile to add some tests.

> add test cases for ACID

> I think the following tests are added
> 1) CTAS into transactional table must be transactional.
> 2) tablesample with buckets from ACID table - judging by HIVE-14967, 
> selecting buckets with nested directories may have bugs on Tez
> 3) insert with union - same reason, if the test doesn't already exist it 
> would be nice to see that bases and deltas are processed correctly given that 
> union creates 2 directories for the results of the same insert
