Varun Vasudev reassigned YARN-160:
----------------------------------
Assignee: Varun Vasudev
> nodemanagers should obtain cpu/memory values from underlying OS
> ---------------------------------------------------------------
>
> Key: YARN-160
> URL: https://issues.apache.org/jira/browse/YARN-160
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: nodemanager
> Affects Versions: 2.0.3-alpha
> Reporter: Alejandro Abdelnur
> Assignee: Varun Vasudev
> Fix For: 2.5.0
>
>
> As mentioned in YARN-2
> *NM memory and CPU configs*
> Currently these values are coming from the config of the NM, we should be
> able to obtain those values from the OS (ie, in the case of Linux from
> /proc/meminfo & /proc/cpuinfo). As this is highly OS dependent we should have
> an interface that obtains this information. In addition implementations of
> this interface should be able to specify a mem/cpu offset (amount of mem/cpu
> not to be avail as YARN resource), this would allow to reserve mem/cpu for
> the OS and other services outside of YARN containers.
