Subject Zombie connection requests?
Date Fri, 27 Jan 2017 20:15:15 GMT
Hello,

I am new to Zookeeper. I was playing with a single node Zookeeper 3.4.6 shipped with Apache
Kafka 0.10.

I was facing some connection issues to Zookeeper hence I decided to stop it, clear all state
(by deleting the dataDir) and start it back up. However after it comes back up, I can see
it log the following lines continuously on the console:


[2017-01-28 01:36:44,312] INFO Accepted socket connection from /10.210.50.240:53503 (org.apache.zookeeper.server.NIOServerCnxnFactory)
[2017-01-28 01:36:44,313] INFO Refusing session request for client /10.210.50.240:53503 as
it has seen zxid 0x50a83 our last zxid is 0x1b client must try another server (org.apache.zookeeper.server.ZooKeeperServer)
[2017-01-28 01:36:44,313] INFO Closed socket connection for client /10.210.50.240:53503 (no
session established for client) (org.apache.zookeeper.server.NIOServerCnxn)

What is really strange is that I keep seeing this even though the machine with IP 10.210.50.240
has been shut down!

What am I missing? I have tried restarting zookeeper and clearing the data directory several
times.

Regards,
Varun
