Jordan Zimmerman commented on ZOOKEEPER-2288:
---------------------------------------------
FYI - Curator now has workaround methods. You can delete "quietly" (Curator
hides the NoNode exception). You can also now do a create-or-set-data whereby
Curator will set the data if the node already exists.
> During shutdown, server may fail to ack completed transactions to clients.

> During shutdown, requests may still be in flight in the request processing
> pipeline. Some of these requests have reached a state where the transaction
> has executed and committed, but has not yet been acknowledged back to the
> client. It's possible that these transactions will not ack to the client
> before the shutdown sequence completes.
