> nodemanagers should obtain cpu/memory values from underlying OS

> Project: Hadoop YARN

> Components: nodemanager

> Reporter: Alejandro Abdelnur
> Assignee: Varun Vasudev
> Fix For: 2.7.0

> 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.
