> Infinite loop with accumulator function in nested foreach
> ---------------------------------------------------------
>
> Key: PIG-1911
> URL: https://issues.apache.org/jira/browse/PIG-1911
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.8.0
> Reporter: Olga Natkovich
> Assignee: Thejas M Nair
> Fix For: 0.8.0
>
> Attachments: PIG-1911.08.1.patch

> Sample script:
> register v_udf.jar;
> a = load '2records' as (f1:chararray,f2:chararray);
> b = group a by f1;
> d = foreach b { sort = order a by f1;
> generate org.udfs.MyCOUNT(sort) as something ; }
> dump d;
> This causes infinite loop if MyCOUNT implements Accumulator interface.
> The workaround is to take the function out of nested foreach into a separate
> foreach statement.
