> Key: PIG-1625
> URL: https://issues.apache.org/jira/browse/PIG-1625
> Project: Pig
> Issue Type: Bug
> Components: documentation
> Affects Versions: 0.7.0
> Reporter: Alan Gates
> Assignee: Corinne Chandel
> Fix For: 0.8.0
>
>
> Currently the docs in
> http://hadoop.apache.org/pig/docs/r0.7.0/piglatin_ref2.html#FOREACH say that
> SAMPLE can be used as an operator in nested foreach. It cannot.
> Also, they do not mention the ability to do projections inside nested
> foreach, such as the following:
> {code}
> A = load '/Users/gates/test/data/studenttab10';
> B = group A all;
> C = foreach B {
> C1 = A.$0;
> C2 = distinct C1;
> generate C2;
> }
> dump C;
> {code}
