> 1) decrease action count repeatedly
> If the AsyncRequestFuture#waitUntilDone return prematurely, user will get the
> incorrect results. Or user will be block by AsyncRequestFuture#waitUntilDone
> as the count is never equal with 0.
> 2) the successive result will be overwrited
> 3) The failed op is added to RetriesExhaustedWithDetailsException repeatedly
> AsyncRequestFutureImpl#receiveMultiAction process the action-lever error
> first, and then add the region-level exception to each action. Hence, user
> may get the various exceptions for the same action (row op) from the
> RetriesExhaustedWithDetailsException.
> In fact, if both of action-level exception and region-lever exception exist,
> they always have the same context. I'm not sure whether that is what
> RetriesExhaustedWithDetailsException want. As i see it, we shouldn't have the
> duplicate ops in RetriesExhaustedWithDetailsException since that may confuse
> users if they catch the RetriesExhaustedWithDetailsException to check the
> invalid operations.
