> Key: PIG-1184
> URL: https://issues.apache.org/jira/browse/PIG-1184
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.6.0
> Reporter: Pradeep Kamath
> Assignee: Daniel Dai
> Fix For: 0.7.0
>
> Attachments: PIG-1184-1.patch, PIG-1184-2.patch

> The following script :
> {noformat}
> -e "a = load 'input.txt' as (f1:chararray, f2:chararray,
> f3:bag{t:tuple(id:chararray)}, f4:bag{t:tuple(loc:chararray)}); b = foreach a
> generate f1, f2, flatten(f3), flatten(f4), 10; b = foreach b generate f1, f2,
> \$4; dump b;"
> {noformat}
> gives the following result:
> (oiue,M,10)
> {noformat}
> cat input.txt:
> oiue M {(3),(4)} {(toronto),(montreal)}
> {noformat}
> If PruneColumns optimizations is disabled, we get the right result:
> (oiue,M,10)
> (oiue,M,10)
> (oiue,M,10)
> (oiue,M,10)
> The flatten results in 4 records - so the output should contain 4 records.
