> PigCombiner.sJobContext and PhysicalOperator.reporter hold references to the WrappedReducer$Context
which in turn holds TezOutputContextImpl which holds references to the buffers in DefaultSorter.
This was causing OOM after the container was reused 2 or 3 times. Debugged this with L17.pig
in pigmix.
