Xuan Gong commented on YARN-513:
--------------------------------
After reading the code in HDFS-3504, we can definitely reuse the existing
RetryPolicy code. We can use RetryPolicies.retryUpToMaximumTimeWithFixedSleep
as defaultPolicy. We can also use RetryPolicies.retryByException to set a
default policy with some explicit handlers for specific exceptions.
> Verify all clients will wait for RM to restart
