    [ https://issues.apache.org/jira/browse/PIG-1871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12999630#comment-12999630 ] 

Ashutosh Chauhan commented on PIG-1871:
---------------------------------------

a = load 'mydata' USING MyLoader();
b0 = filter a BY
    (   (ds < '20091103' )
     or (action == 'continue' )
    );
b = filter b0 BY
    (   (ds < '20091103' and age < 50)
     or (action == 'continue' and age > 100)
    );
c = foreach b generate ds, action, age, data;
store c into ':OUTPATH:';
...

fails with message:

Grunt - ERROR 1112: 
Unsupported query: 
You have an partition column (datestamp ) in a construction like: (pcond  and ...) or (pcond and ...) where pcond is a condition on a partition column.

In this testcase ds and action are partition columns while age is not. So, pig decided it cannot split the filter and can't push the partition filter to the loader. In such a condition instead of dying, Pig should disable partition filter push up and continue.
