> 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.
