> YARN-6344 introduces a new parameter
> {{yarn.scheduler.capacity.rack-locality-additional-delay}} in
> capacity-scheduler.xml, we need to add some documentation in
> {{CapacityScheduler.md}} accordingly.
> Moreover, we are seeing more and more clusters are separating storage and
> computation where file system is always remote, in such cases we need to
> introduce how to compromise data locality in CS otherwise MR jobs are
> suffering.
