Ming Ma commented on MAPREDUCE-5790:
------------------------------------
It appears https://issues.apache.org/jira/browse/MAPREDUCE-5650 set
<name>mapreduce.task.profile.map.params</name>
<value>${mapreduce.task.profile.params}</value>
The reading code doesn't like it.
If you remove the default setting, things will work fine. Perhaps we can leave
the default value empty so profile works out of box.
> Default map hprof profile options do not work
