> AbstractYarnScheduler has a configured wait time during which it reports the maximum
resources from the configuration instead of the actual resources available in the cluster.
However, the first query after the wait time expiration is responded by the configured maximum
resources instead of the actual maximum resources. This can result in a app submission to
fail with an InvalidResourceRequestException (will attach a unit test in the patch) since
the maximum resources reported by the RM is different than the one it sanity checks against
at app submission.
