Flavio Junqueira commented on KAFKA-2587:
-----------------------------------------
bq. is it possible that the sequential node doesn't exist yet on the new ZK
server?
When a client re-connects to a different server, it makes sure that the server
has seen at least as many updates as the previous one by checking the latest
zxid of the new server it is connecting to. Consequently, if a znode Z is
observable to a client while the client is connected to server A and the client
successfully re-connects to B, then the client must be able to see Z through B.
Assuming that the znodes under /acl_changes aren't ephemerals and haven't been
deleted, it is not possible that the Authorizer receives a watch notification
while connected to server A, re-connects to server B, and doesn't see the
change that triggered the notification while connected to B.
