> In current ObserverReadProxyProvider implementation, we use the following
> code to invoke msync RPC.
> {code:java}
> getProxyAsClientProtocol(failoverProxy.getProxy().proxy).msync(); {code}
> But msync RPC maybe send to Observer NameNode in this way, and then failover
> to Active NameNode. This can be avoid by applying this patch.
