We have ambari cluster with 3 Kafka hosts
We want to delete all kafka brokers from the cluster ( by option in ambari – delete hosts )
We succeeded to delete the first two kafka – kafka01 and kafka02
but when we try to delete the last kafka – kafka03 we get the following:
Unable to delete host - this host cannot be deleted since the following master components do not have any other instnaces: Kafka Broker, schema_registry,
To delete this host, you must first add all the components listed above to other hosts
How to resolve this issue?
you need to remove Kafka service first from the whole cluster to be able to delete all master
as you try to delete the last master in Kafka service
It's advised to stop all the components and move master services and delete the host.
Remove the kafka service and try to delete the host.
