> Components: impl
> Affects Versions: 0.12.0

> This is a regression from PIG-3461 - rewrite of partition filter optimizer.
> Here is an example that demonstrates the problem:
> {code:title=two filters}
> b = FILTER a BY (dateint >= 20130901 AND dateint <= 20131001);
> c = FILTER b BY (event_id == 419 OR event_id == 418);
> {code}
> {code:title=one filter}
> b = FILTER a BY (dateint >= 20130901 AND dateint <= 20131001) AND (event_id
> == 419 OR event_id == 418);
> {code}
> Both dateint and event_id are partition columns. For the 1 filter case, the
> whole expression is pushed down whereas for the 2 filter case, only (event_id
> == 419 OR event_id == 418) is pushed down.
