PushUpFilter: Filter after skew LOJoin generates an error
---------------------------------------------------------

                 Key: PIG-910
                 URL: https://issues.apache.org/jira/browse/PIG-910
             Project: Pig
          Issue Type: Bug
          Components: impl
    Affects Versions: 0.3.0
            Reporter: Daniel Dai
             Fix For: 0.4.0


The script is:
A = load 'a' as (user:chararray, action, timespent, query_term, ip_addr, timestamp, estimated_revenue,
page_info, page_links);
alpha = load 'b' as (user:chararray, action, timespent, query_term, ip_addr, timestamp, estimated_revenue,
page_info, page_links);
C = join A by user, alpha by user using "skewed" parallel 40;
D = filter C by A::user == 'aaa';
store D into 'L5out';

Stack trace is:
