Webhdfs retry policy for unresolved hosts

    Description

      DNs that fail to resolve the NN for the rpc connection will cause the webhdfs client to fail w/o retries. The webhdfs retry policy should be modified so it will try another DN.

      Webhdfs should use RetryPolicies.retryByRemoteException in addition to the network FailoverOnNetworkExceptionRetry policy. The NameNodeProxies check for a resolved address should throw a distinct exception (like UnknownHostException) for the remote ex policy to catch.
