Just rerun mqsisetdbparms with the relevant parameters. The new password will replace the old one. Remember that you have to bounce the Node for the change to take effect.
Have fun

Sounds like your zookeeper or kafka nodes aren't in quorum.
Talk to your Kafka admins. If they give you lip, ask them sweetly if they've got 5 zookeepers running, to ensure non-disruptive maintenance...
From several feet away.

Ok.
Restart both the kafka and zookeeper instances and try again.

how many kafkas and how many zookeepers?
You need three zks at a minimum. (even if just on docker images running on your laptop)

You need three zookeepers.
Not one. Not two. Three.
