sam liu commented on MAPREDUCE-6204:
------------------------------------
In Hadoop 2.x, the property JobConf.MAPRED_TASK_JAVA_OPTS is deprecated, and
hadoop will ignore this property directly without replacing its new
values(MAPRED_MAP_TASK_JAVA_OPTS and MAPRED_REDUCE_TASK_JAVA_OPTS).
This issue will cause test TestJobCounters fail on PPC64 platform sometimes, as
PPC64 JVM sometimes comsumes more memory when executing map/reduce tasks and
might encounter JVM crashing issue once the default heap size is exhausted.
> TestJobCounters should use new properties instead
> JobConf.MAPRED_TASK_JAVA_OPTS
