Xiang Li commented on PIG-4967:
-------------------------------
MAPREDUCE-6762 fixes this issue on Hadoop side. When status=null, the logic is
changed to get job name from the super class of Job, which is JobContextImpl,
and eventually get job name from conf.
The patch is applied into branch-2 (and trunk) of Hadoop, which will be picked
up by the next 2.x release (maybe 2.9?). Pig currently picks up Hadoop 2.6.0 in
trunk. I think I need to add a TODO in the pig fix to remind revisiting it
after Pig picks up a Hadoop version with MAPREDUCE-6762 applied.
