Namit Jain commented on HIVE-1534:
----------------------------------
The approach looks OK - I will look into the code for more detailed comments.
One general comment was that you also need to account for progress if the join
filters filter all the rows.
The task tracker may be thought of an un-responsive. Look at the filter
operator, we send a progress in
that case if there are 'n' consecutive rows filtered out.
> Join filters do not work correctly with outer joins
