> Key: HDFS-14543
> URL: https://issues.apache.org/jira/browse/HDFS-14543
> Project: Hadoop HDFS
> Issue Type: Task
> Components: rbf
> Reporter: xuzq
> Assignee: xuzq
> Priority: Major
>
> 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.
