Arun C Murthy updated MAPREDUCE-1207:
-------------------------------------
Status: Open (was: Patch Available)
Sorry to come in late, the patch has gone stale. Can you please rebase? Thanks.
Given this is not an issue with MRv2 should we still commit this? I'm happy to,
but not sure it's useful. Thanks.
We should port to NodeManager...

> It will be useful for allow cluster-admins to set some java options for child
> map/reduce tasks.
> E.g. We've had to ask users to set -Djava.net.preferIPv4Stack=true in their
> jobs, it would be nice to do it for all users in such scenarios even when
> people override mapred.child.{map|reduce}.java.opts but forget to add this.
