Kafka still aware of old zookeeper nodes

I had 3 zookeeper nodes. I added 3 new ones and shut down the old 3.

The server.log shows Closing socket connection error to the old IPs. I
rebooted the kafka server entirely but it still somehow seems aware of
these servers.

Any ideas what's up?

Not sure if this is the best way to do this, but my zookeeper.connect is
set to a DNS alias which points to a load balancer for 3 zookeeper nodes.

I was trying this to see if I could have the kafka config dynamic and allow
me to change/scale whatever I wanted with zookeeper and not have to ever
mess with the config for kafka.

Thanks for your comments.

Have you changed

zookeeper.connect=

in server.properties.

A better procedure for replacing zookeeper nodes would be to shutdown one
and install the new one with the same ip. This can easily be done to a
running cluster.
