Namit Jain commented on HIVE-1060:
----------------------------------

Can you add a test in negative tests ?

Also, do you think it would be simpler to check for "=" instead of the check you have added.

> In some SQL dialect, we support this kind of syntax as a shortcut of "a.key = b.key".
> We should output an error for this. Currently we are allowing this because we might have
implicit type conversion from String to Boolean.
