Description
We do not handle re-aliasing of an existing alias - this should be handled correctly.
The following script should work:
a = load 'studenttab10k'; b = filter a by $1 > '25'; c = b; -- use b d = cogroup b by $0, a by $0; e = foreach d generate flatten(b), flatten(a); dump e -- use c f = cogroup c by $0, a by $0; g = foreach f generate flatten(c), flatten(a); dump g;
