How to purge everything after deleting service

majnam — Fri, 20 Jan 2017 01:35:12 GMT

My question is next,

how to delete every single data after I delete service directly from Ambari. For example, how to delete every config file, every data, every topic of Kafka after deleting Kafka service from Ambari. Or even better question, how to completly reinstall Kafka so I have fresh start without any topic or any data. Thank you! 🙂

so, if you delete the service, I think it should already removed the topics. But mainly you need to check on zookeeper, and see whether any information regarding broker is there? and you can also check whether any data is left on the directory that kafka data located.

This is an answer is someone will deal with this:

First connect with zkCLi

bin/zkCli.sh -server server:port

afterwards find the path you need. I needed /brokers file and than if you want to delete it enter thi

$ ls /brokers
$ rmr /brokers
