------------------------------------
maybe just updating the doc to mention this?
> Allow passing arguments to custom Partitioners

> URL: https://issues.apache.org/jira/browse/PIG-2204
> Project: Pig
> Issue Type: Improvement
> Reporter: Dmitriy V. Ryaboy

> Currently, this works:
> {code}
> y = group x by $0 partition by MyPartitioner PARALLEL 2;
> {code}
> However, passing an argument to the partitioner constructor does not work,
> and dies with a misleading error:
> {code}
> y = group x by $0 partition by MyPartitioner(0) PARALLEL 2;
