Thejas M Nair commented on HIVE-4350:
-------------------------------------
As this is an optional keyword that does not change the plan, I think it will
be safe to modify an existing test case to use this keyword, instead of adding
a new one. That we can avoid adding couple of seconds to the test runtime.
> support AS keyword for table alias
