------------------------------

FAILURE: Integrated in Hadoop-Hdfs-trunk #1874 (See 
[https://builds.apache.org/job/Hadoop-Hdfs-trunk/1874/])
YARN-2531. Added a configuration for admins to be able to override app-configs 
and enforce/not-enforce strict control of per-container cpu usage. Contributed 
by Varun Vasudev. (vinodkv: rev 9f6891d9ef7064d121305ca783eb62586c8aa018)

> The other dimension to this is determinism w.r.t performance. Limiting to 
> allocated cores overall (as well as per container later) helps orgs run 
> workloads and reason about them deterministically. One of the examples is 
> benchmarking apps, but deterministic execution is a desired option beyond 
> benchmarks too.

> It would be nice to have an option to let admins to enforce strict cpu limits 
> for apps for things like benchmarking, etc. By default this flag should be 
> off so that containers can use available cpu but admin can turn the flag on 
> to determine worst case performance, etc.
