> 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.
