Yongzhi Chen commented on HIVE-13588:
-------------------------------------
[~ctang.ma], Does your fix need changing location of
tskRun.setOperationLog(OperationLog.getCurrentOperationLog()); ?
>From HIVE-9120 , it looks like the setOperationLog is not needed when
>hive.exec.parallel is false.
> NPE is thrown from MapredLocalTask.executeInChildVM
