Sergey created PIG-3347:
---------------------------

             Summary: Store invocation in local mode brings sire effect
                 Key: PIG-3347
                 URL: https://issues.apache.org/jira/browse/PIG-3347
             Project: Pig
          Issue Type: Bug
          Components: grunt
    Affects Versions: 0.11
         Environment: local mode
            Reporter: Sergey


The problem is that intermediate 'store' invocation "changes" the final store output. Looks
like it brings some kind of side effect. We did use 'local' mode to run script
here is the input data:
1
1
Here is the script:
{code}
a = load 'test';

a_group = group a by $0;
b = foreach a_group {
  a_distinct = distinct a.$0;
  generate group, a_distinct;
}
--store b into 'b';
c = filter b by SIZE(a_distinct) == 1;
store c into 'out';
{code}
We expect output to be:
1 1
The output is empty file.

Uncomment {code}--store b into 'b';{code} line and see the diffrence.
Yuo would get expected output.
