------------------------------------

             Summary: RPC client fails too quickly when server connection limit is reached
                 Key: HADOOP-12861
                 URL: https://issues.apache.org/jira/browse/HADOOP-12861
             Project: Hadoop Common
          Issue Type: Bug
          Components: ipc
    Affects Versions: 2.7.0
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp


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.
