Brock Noland commented on HIVE-4009:
------------------------------------
Too be clear, although MAPREDUCE-5001 improves the situation in that an
exception is not throw, it's still possible for LJR to return null an fail.
This happens on hosts which are very busy. Let's just not the racy status
section of code when in local mode.
> CLI Tests fail randomly due to MapReduce LocalJobRunner race condition
