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
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.
