Allen Wittenauer resolved MAPREDUCE-187.
----------------------------------------
Resolution: Won't Fix
I'm going to close this as Won't Fix given the usage of cgroups and more.
> Generalize mapred.child.ulimit so as to help setting up other limits.

> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Vinod Kumar Vavilapalli
>
> Currently mapred.child.ulimit cannot be used for anything other than for
> setting virtual limits. It is hardcoded to set virtual mem limits (ulimit -v)
> only. This should be changed so that other limits like open file descriptors,
> max user processes etc can be set.
