we have cluster HDP 2.6.4 with 3 kafka brokers ( each broker installed on master machine )

we want to remove the service - KAFKA by API from the AMBARI

what is the API to delete the kafka-broker on each master machine?

what is the API to remove the KAFKA service ?

what the other steps to removed completely the kafka-brokers from the master machines?

1. First Stop the Kafka Service

# curl -i -u admin:admin -H "X-Requested-By: ambari" -X PUT -d '{"RequestInfo":{"context":"_PARSE_.STOP.KAFKA","operation_level":{"level":"SERVICE","cluster_name":"NewCluster","service_name":"KAFKA"}},"Body":{"ServiceInfo":{"state":"INSTALLED"}}}' http://newhwx1.example.com:8080/api/v1/clusters/NewCluster/services/KAFKA

2. Delete the Kafka Service:

# curl -i -u admin:admin -H "X-Requested-By: ambari" -X DELETE http://newhwx1.example.com:8080/api/v1/clusters/NewCluster/services/KAFKA

Yes, the complete Kafka service (including all the brokers will be deleted) when we will make the 2nd call.

But If you just want to delete a particular kafka Broker then you will need to make the API call on individual host_components.

# curl -i -u admin:admin -H "X-Requested-By: ambari" -X DELETE http://newhwx1.example.com:8080/api/v1/clusters/NewCluster/hosts/kafkahost1.example.com/host_components/KAFKA_BROKER

Should we also delete Kafka topics before deleting the service? Will the topics still remain after deleting the service?
