Alan Gates reassigned PIG-414:
------------------------------

    Assignee: Santhosh Srinivasan

This affects more than just describe.  If you have a query like:

{code}
a = load 'infile';
split a into a1 if $0 > 'm', a2 if $0 <= 'm';
b = cogroup a1 by $1, a2 by $1;
c = foreach b generate flatten(a1), flatten(a2);
store c into 'outfile';
{code}

it will fail saying that a1 and a2 are not valid aliases in b at the foreach line.
