Robert Kanter commented on OOZIE-1372:
--------------------------------------
[~rohini], would you be able to take care of this? I'm not really sure what
values would be reasonable and you seem more familiar with the issue.
> When using uber mode, Oozie should also make the AM container size larger

> Affects Versions: trunk

> Fix For: trunk
>
>
> OOZIE-1335 made Oozie use uber mode for the launcher job by default. We
> should also increase the AM container size in case the launcher job needs
> more memory (e.g. a Pig job).

> yarn.app.mapreduce.am.resource.mb is easy and you can just set and overwrite.
> You will have to do some string manipulation with
> yarn.app.mapreduce.am.command-opts or append hoping the last values will take
> effect. Not sure if there are jvm's (IBM or openjdk) which will take the
> first value.
