xuzq updated HDFS-14543:
------------------------
Description:
Currently RouterRpcClient will retry when the remote exception is
RetryException.
And it will use one handler to retry 3 times, if the remote exception is always
RetryException.
Although there is no sleep between retries, but it may costs some other
resources.
So, RouterRpcClient show return the RetryException to client if the name node
returns RetryException, and do sleep at client.
After sleep some times, client can request the same Router.
