[jira] [Updated] (HADOOP-12861) RPC client fails too quickly when
server connection limit is reached

> The NN's rpc server immediately closes new client connections when a connection limit is reached. The client rapidly retries a small number of times with no delay which causes clients to fail quickly. If the connection is refused or timedout, the connection retry policy tries with backoff. Clients should treat a reset connection as a connection failure so the connection retry policy is used.
