Cheolsoo Park commented on PIG-3461:
------------------------------------
I just committed PIG-3510 to 0.12 branch.
Regarding seriousness, this doesn't make jobs fail, but it has definitely had
production impact since it make jobs run longer. I would vote for another RC,
but if we can release 0.12.1 soon enough after 0.12.0 is out, that'll be fine
too.

> Current algorithm for Partition Filter pushdown identification fails in
> several corner cases. We need to rewrite its logic so that it works in all
> cases and does the maximum possible filter pushdown.
