Ashutosh Chauhan commented on HIVE-12328:
-----------------------------------------
I think ask is to do this check in compile phase that join condition is valid.
Since, such a check is absent in compile time, user is greeted with exception
at runtime (as evident from stacktrace).
> Join On clause needs a semantic check to verify expression is boolean
