Arun C Murthy commented on MAPREDUCE-5311:
------------------------------------------
To Sandy's point - several folks do use mapred.cluster.(map,reduce).memory.mb,
so it will be a big BC break for them.
Also, what does this mean for BC after we spent all the time fixing
MAPREDUCE-5108.
> Replace SLOTS_MILLIS counters with MEM_MILLIS
