Jason Lowe commented on MAPREDUCE-5653: --------------------------------------- Thanks for the patch, Mithun. Was there a reason addDefaultResource(DISTCP_DEFAULT_XML) wasn't used? I think that should accomplish the same goal without explicit config iteration on DistCp's part, but haven't tried it to verify. Is there a concern that distcp-default.xml could pollute other configurations if DistCp is not used in isolation? > 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: trunk, 0.23.9, 2.2.0 > Reporter: Mithun Radhakrishnan > Assignee: Mithun Radhakrishnan > Attachments: MAPREDUCE-5653.branch-0.23.patch, > MAPREDUCE-5653.branch-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.
