> In current Async DFS implementation, file system calls are invoked and
> returns Future<?> immediately to clients. Clients call Future#get to retrieve
> final results. Future#get internally invokes a chain of callbacks residing in
> ClientNamenodeProtocolTranslatorPB, ProtobufRpcEngine and ipc.Client. The
> callback path bypasses the original retry layer/logic designed for
> synchronous DFS. This proposes refactoring to make retry also works for Async
> DFS.
