I have a cluster with one node that has 3 namespaces: mynamespace, test, bar. Each one has a replication factor of 2.
I want to add a second node with only 1 namespace: mynamespace. In brief I want to remove test and bar with no downtime.
When I do that, I see a lot of errors on node#2 complaining that it does not find test and bar.
Please would you suggest a way to remove namespace without any down time?
