> Move handling of concurrent client fail-overs to RetryInvocationHandler
> -----------------------------------------------------------------------

> Key: HADOOP-7717
> URL: https://issues.apache.org/jira/browse/HADOOP-7717
> Project: Hadoop Common
> Issue Type: Improvement
> Components: ipc
> Affects Versions: 0.23.0, 0.24.0
> Reporter: Aaron T. Myers
> Assignee: Aaron T. Myers
> Fix For: 0.24.0, 0.23.3
>
> Attachments: HADOOP-7717.patch, HADOOP-7717.patch

>
> Currently every implementation of a {{FailoverProxyProvider}} will need to
> perform its own synchronization to ensure that multiple concurrent failed
> calls to a single client proxy object don't result in multiple client fail
> over events. It would be better to put this logic in
> {{RetryInvocationHandler.invoke}}.
> This is based on feedback provided by Todd in [this
