>    Affects Versions: 0.8.0
>            Reporter: Olga Natkovich

> 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.
