unexpected server response
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 03:46:50,655:1207(0xf26ffb40):ZOO_INFO@check_events@2345: initiated connection to server [128.0.0.5:61728]
2016-04-11 03:46:50,658:1207(0xf26ffb40):ZOO_INFO@check_events@2397: session establishment complete on server [128.0.0.5:61728], sessionId=0x4000001852c000c, negotiated timeout=20000
5. Some times I find errors like below:
2016-04-11 03:46:50,662:1207(0xf26ffb40):ZOO_ERROR@handle_socket_error_msg@2923: Socket [128.0.0.5:61728] zk retcode=-2, errno=115(Operation now in progress): unexpected server response: expected 0x570b82fa, but received 0x570b82f9
1.
zoo_get returns (-2) indicating that ZRUNTIMEINCONSISTENCY<http://zookeeper.sourcearchive.com/documentation/3.2.2plus-pdfsg3/zookeeper_8h_bb1a0a179f313b2e44ee92369c438a4c.html#bb1a0a179f313b2e44ee92369c438a4c9eabb281ab14c74db3aff9ab456fa7fe>
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,
Pramod
