> The problem is in appendAndSync method, we will issue an AsyncDFSOutput.sync
> if syncFutures is not empty. The SyncFutures in syncFutures can only be
> removed after an AsyncDFSOutput.sync comes back, so before the
> AsyncDFSOutput.sync actually returns, we will always issue an
> AsyncDFSOutput.sync after an append even if there is no new sync request.
