Varun Vasudev commented on YARN-2440:
-------------------------------------
[~beckham007] the current implementation of Cgroups uses cpu instead of cpuset,
probably due to the flexibility offered(sharing the cores is handled by the
kernel). Is there any particular benefit to cpuset?
> Cgroups should allow YARN containers to be limited to allocated cores
