Thanks for the quick response Flavio,
Just to iterate what i understand.
1. swap the zookeeper nodes one by one, add new node and remove one old
node: i have one more question here, what about kafka cluster configuration,
is it ok to keep old 3 zookeeper nodes as still there are 2 old nodes
available?
2. just before swapping the 3rd node (leader node), i think we need to
change the kafka cluster configuration to point to new zookeeper nodes and
bounce the kafka cluster. is it correct approach or do we need to take a
brief outage and swap the 3rd (leader) node and restart the kafka cluster
with new ZK nodes configuration.
Thanks for your help.
