Mithun Radhakrishnan commented on MAPREDUCE-5653:
-------------------------------------------------
Hey, [~rdsr]. (Long time! :]). Hello, [~aw]. Apologies for the unreasonably
delayed response.
Thank you both for addressing this. I agree. Removing those properties from the
default.xml does solve the immediate problem.
It's a different matter that the initialization path is still incorrect
(because of how/when default.xml is loaded). This might not be of consequence.
Should that change later, we'll tackle that in a separate JIRA.
Cheers.

> When a DistCp job is run through Oozie (through a Java action that launches
> DistCp), one sees that mapred.child.java.opts as set from the caller is
> honoured by DistCp. But, DistCp doesn't seem to honour any overrides for
> configs mapreduce.[map,reduce].memory.mb.
> Problem has been identified. I'll post a patch shortly.
