Rohini Palaniswamy commented on PIG-4202:
-----------------------------------------

AM (job commit). All static variables/thread locals are cleared up in 
PigProcessor.close(). So we don't have any problem with container reuse of 
tasks. But nothing of that sort is done with AM and so we are facing issues 
when AM container is reused and if there are static variables initialized with 
the OutputCommitter.

> UDFContext.isFrontend return true for OutputCommitter in local mode

> We switch to use UDFContext.isFrontend in PIG-4187. However, it does not work 
> as expected in local mode. This causes some local mode test fail 
> (TestOrcStoragePushdown.createInputData).
