Allen Wittenauer commented on MAPREDUCE-5653: --------------------------------------------- bq. Allen, do you think there's more than just this one Xmx passthrough that's affecting DistCP? Yes. but those are outside the scope of this jira. bq. Hadn't seen MAPREDUCE-5785. Agree that that's an excellent direction. As I mentioned way above, for the same reasons that '5785 is in trunk, this change is also only in trunk. Hypothetically, they should work very well together. > DistCp does not honour config-overrides for mapreduce.[map,reduce].memory.mb > ---------------------------------------------------------------------------- > > Key: MAPREDUCE-5653 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5653 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: distcp > Affects Versions: 0.23.9, 2.2.0 > Reporter: Mithun Radhakrishnan > Assignee: Ratandeep Ratti > Fix For: 3.0.0 > > Attachments: MAPREDUCE-5653.branch-0.23.patch, > MAPREDUCE-5653.branch-2.patch, MAPREDUCE-5653.trunk.2.patch, > MAPREDUCE-5653.trunk.patch > > > 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.
