> Currently, if a pig script job contains multiple map-reduce jobs, each job
> will serialize all map-reduce job plan into JobConf. The reason is
> PhysicalOperator.inputs is built in Physical plan and in fact it chains all
> the jobs without regard to map-reduce boundary. Further, when we only want to
> serialize POStore, we serialize this whole plan again due to POStore.inputs.
> This should be fixed.
