Namit Jain commented on HIVE-935:
---------------------------------

Also, would it be possible to add the following tests:

1. A negative test where the explode is returning 2 columns, but you have specified 2 aliases.
2. A positive test where 2 column aliases are being returned - you can add a dummy function in contrib/test
    which returns the same value twice.
