------------------------------
FAILURE: Integrated in Hadoop-Mapreduce-trunk #1901 (See
[https://builds.apache.org/job/Hadoop-Mapreduce-trunk/1901/])
YARN-2001. Added a time threshold for RM to wait before starting container
allocations after restart/failover. Contributed by Jian He. (vinodkv: rev

> After failover, RM may require a certain threshold to determine whether it’s
> safe to make scheduling decisions and start accepting new container requests
> from AMs. The threshold could be a certain amount of nodes. i.e. RM waits
> until a certain amount of nodes joining before accepting new container
> requests. Or it could simply be a timeout, only after the timeout RM accepts
> new requests.
> NMs joined after the threshold can be treated as new NMs and instructed to
> kill all its containers.
