Prasanth Jayachandran commented on HIVE-14376:
----------------------------------------------
Actually it gets worse there are 13 more tests for schema evolution on text.
Replacing INSERT INTO queries is extremely laborious task. Most q files are
>800 LOC. All of the select queries also have order by.
> Schema evolution tests takes a long time
