Review comment:
add a null check for columnNames? getColumnNames returns null too.

Review comment:
Also, Is it a positive test case or negative? I see that there is an
expected error but we are doing the positive validations too. We should break
this into two, right?

Review comment:
Won't adding a qtest be better?
You are explicitly doing `tblUpdated.getSd().getBucketCols()` and updating
them in the test. qtest will check end to end flow and you don't need to bother
about getting Sd and updating the cols explicitly (Just a single alter table
will do the trick).
