-------------------------------------------------------

TezChild.ContainerExecutionResult is static in TEZ-870. It is possible that when we are running two containers in parallel in Local Mode. It is possible that the later container overwrites earlier container's result. Is this correct, [~sseth] ?

> Pig on Tez allows user to submit parallel DAGs in a single pig script. Those DAGs could be independent and concurrent. Current LocalMode may encounter some problems when concurrent parallel DAGs are submitted.
