Removing Kakfa broker through Ambari

techiegreenhorn — Thu, 28 Jan 2016 08:29:31 GMT

Hi,

I have installed Kafka on my HDP cluster using Ambari. With the default configuration, Ambari installed only one Kafka broker. However, now had installed another two Kafla brokers in the clusters. My requirement is to remove the Kafka broker on the initial machine, on which it was installed.

When I checked Ambari, it doesn't seem to allow me to delete the Kafka broker on a machine, though it allows to install. May I know how to remove a Kafka broker from a node in the HDP cluster, preferably through Ambari?

Thanks

@Greenhorn Techie

Version2.2.0.0

I see in Ambari to delete after adding new broker.

@Neeraj Sabharwal not if you add additional brokers after running Kafka for some time. It is not that easy, Kafka assigns broker ids in sequential order and there's some magic needed to keep the order after adding new brokers.

@Neeraj Sabharwal The option I could see at the moment is Stop and the Delete is disabled. Should I first stop it and then delete it?

@Greenhorn Techie Please try that..In my case , it was stopped but I could not delete it without adding new broker "I had only one broker in my cluster"

Would love to see the outcome after stopping it
