Whenever a session is expired by ZooKeeper I see the following messages (one per consumer I think) in the ZooKeeper log:
2014-03-25 00:05:12,953 - INFO [ProcessThread:-1:PrepRequestProcessor@419] - Got user-level KeeperException when processing sessionid:0x344f675fcee0164 type:create cxid:0x7566 zxid:0xfffffffffffffffe txntype:unknown reqpath:n/a Error Path:/consumers/optimizer-group/owners/optimizer-default-topic/724 Error:KeeperErrorCode = NodeExists for /consumers/optimizer-group/owners/optimizer-default-topic/724 Is this normal? Something the Kafka consumer recovers from?
