Hari Sankar Sivarama Subramaniyan commented on HIVE-12328:
----------------------------------------------------------

A qn here, is it possible to catch this error at an earlier phase, say FilterOperator.initializeOp()

> SQL join query fails at query runtime with a poor error message if the expression in
the on clause of join is not a boolean.
> Hive should give a proper error message at runtime.
