[jira] Created: (HADOOP-6667) RPC.waitForProxy should retry through NoRouteToHostException

RPC.waitForProxy should retry through NoRouteToHostException
------------------------------------------------------------

                 Key: HADOOP-6667
                 URL: https://issues.apache.org/jira/browse/HADOOP-6667
             Project: Hadoop Common
          Issue Type: Improvement
          Components: ipc
    Affects Versions: 0.21.0, 0.22.0
            Reporter: Todd Lipcon
            Priority: Minor


RPC.waitForProxy already loops through ConnectExceptions, but NoRouteToHostException is not a subclass of ConnectException. In the case that the NN is on a VIP, the No Route To Host error is reasonably common during a failover, so we should retry through it just the same as the other connection errors.
