Aegeaner commented on FLINK-6958:
---------------------------------

Maybe you could set a CountDownLatch, and call countdown in case of both complete and failure.

> when use Async I/O with UnorderedStreamElementQueue, the queue will always full if you don't  call the AsyncCollector.collect to ack them.
> Timeout shall collect these entries when the timeout trigger,but it isn't work
> I debug find,
> when time out, it will call resultFuture.completeExceptionally(error);
> but not call  UnorderedStreamElementQueue.onCompleteHandler
> it will cause that async i/o hang always
