Arun C Murthy commented on MAPREDUCE-3264:
------------------------------------------
We need to investigate further, but maybe you can set it to ${user} in
mapred-site.xml or better, mapred-default.xml?
> mapreduce.job.user.name needs to be set automatically

> Key: MAPREDUCE-3264

> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.0
> Reporter: Todd Lipcon
> Priority: Blocker
>
> Currently in MR2 I have to manually specify mapreduce.job.user.name for each
> job. It's not picking it up from the security infrastructure, at least when
> running with DefaultContainerExecutor. This is obviously incorrect.
