> AM runs out of memory when trying to respond to getTask() calls from
> container for a vertex with large number of outputs (usually the case with
> multi-query when you group by on multiple dimensions). Problem is with the
> size of payload config associated with PigProcessor, Input and Output. When
> there is >10 outputs size of the payload considerably increases causing
> memory pressure.
