Thank you for your response!
Just out of curiosity, what is this masterslave:() transport is about then?
Also, if I don't configure network connection will
updateClusterClientsOnRemove parameter take effect?
My main concern is that clients will go into stuck state during/after the
failover. I'm not sure if everything I need is just handle this in the code
with TransportListener or do I need to set updateClusterClientsOnRemove and
updateClusterClients on the broker side to make failover smooth?

Hi
No need to use networkConnector with master/slave.
Just use failover on the client side.
So basically,
1. Brokers side, you shared the same filesystem (using NFS, LUN, whatever), and
you configure kahadb to point on the same filesystem in activemq.xml 2. On
client side, you can failover:(master,slave) on the brokerURL to allow client
to automatically switch to “new” master
