Namit Jain commented on HIVE-1534:
----------------------------------
What I meant to say was the following:
People are running queries in the warehouse with the expected wrong semantics -
if we suddenly fix this, the queries will break.
We need to give some time to everyone to change their queries to use a
sub-query if they want the filter to be pushed up.
Adding the above config, parameter seems like the only choice - we can try to
remove this parameter before 0.7 goes out
(if everyone agrees), but we need it right now for deployment
> Join filters do not work correctly with outer joins
