Hemanth Yamijala commented on MAPREDUCE-979:
--------------------------------------------
To be clear, mapred-default in hadoop is updated to not have
mapred.task.maxvmem. However, M/R applications like PIG could bundle their own
mapred-default which, if not updated, would break.
> JobConf.getMemoryFor{Map|Reduce}Task doesn't fallback to newer config knobs
> when mapred.taskmaxvmem is set to DISABLED_MEMORY_LIMIT of -1
