Rohini Palaniswamy commented on PIG-4760:
-----------------------------------------
bq. Actually the MR counter is completely redundant and should be removed.
It is used by Oozie and cannot remove it.

jobStatsGroup.put("HADOOP_COUNTERS",
toJSONFromCounters(jobStats.getHadoopCounters()));

> PIG-4529 reveal a MR counter limit issue imposed to Pig. The original fix
> won't work in Oozie since Oozie launcher already imposed counter limit and
> Pig cannot change it (there is an internal flag in Limits to make sure it
> does not init twice).
> Actually the MR counter is completely redundant and should be removed.
