> 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.
