> PendingAddOp is set to completed when it meets ack quorum.
> {code}
> if (ackSet.addBookieAndCheck(bookieIndex) && !completed) {
> completed = true;
> LOG.debug("Complete (lid:{}, eid:{}).", ledgerId, entryId);
> // when completed an entry, try to send success add callbacks in
> order
> lh.sendAddSuccessCallbacks();
> }
> {code}
> responses are ignored after completed flag is set.
> {code}
> if (completed) {
> // I am already finished, ignore incoming responses.
> // otherwise, we might hit the following error handling logic,
> which might cause bad things.
> return;
> }
> {code}
> It is not a correctness problem, but it would introduce performance issue
> during ensemble change. A callback (could be acknowledge before ensemble
> change) has to be delayed to ensemble change completion.
