in a multi master (3 masters) Kudu installation deployed by Cloudera Manager (parcels CDH, version 5.13) is it possible to migrate one of the masters into a newly added host in CM? Is there any Cloudera documentation how to move a master role?
I have found only this:

It's possible, but I don't think there's a guide for this exact procedure. Here's one approach that directly moves the contents of one machine to another, assuming you want to move from "masterA,masterB,masterC" to "masterA,masterB,masterD":
Also if you're using Impala, you'll want to invalidate metadata to pick up the new masters.
Hope this helped!
