unexpected server response ZRUNTIMEINCONSISTENCY
Re-posting this query again as have not got this issue resolved.
Appreciate your comments on this query.
Hi Folks,
I am hitting an error in my C client code and below are the set of
operations I perform: 1. Zookeeper Client connected to Zookeeper server S1
and a new server S2 gets added. 2. monitor zookeeper server config at the
client and on change of server config, call zoo_set_server from the client
3. client can issue operations like zoo_get just after the call to
zoo_set_servers 4. I can see that the zookeeper thread logs connect to the
new server just after the zoo_get call 2016-04-11

What is the issue here? should I be retry the operation zoo_get operation?
Or should I wait for the zoo_set_server to complete (like wait for the
connection establishment notification) Thanks,

This is being discussed in ZOOKEEPER-2455, yes?

+1. I have also observed this. I currently deal with it by retrying the
operation when I get ZRUNTIMEINCONSISTENCY. If this is the recommended
procedure, maybe we should update the documentation.
Thanks and regards,
