> {code}
> A = load 'i3.txt' as (k,v);
> L = FILTER A BY k == 'k1';
> B = GROUP A BY k PARTITION BY SimpleCustomPartitioner PARALLEL 3;
> C = FOREACH B GENERATE FLATTEN(A) PARALLEL 3;
> STORE C INTO 'output1';
> STORE L INTO 'output2';
> {code}
> For the above script the custom partitioner mentioned in the GROUP BY
> statement is ignored by Pig.
> To workaround this issue I had to disable Multiquery or put exec statements
> in between.
> The configuration is getting missed out while the Physical plan is getting
> converted into the MR plan.
> (Note the POGlobalRearrange is visited on a different MROper than what the
> actual MRPlan returns)
