@Nilesh@Geoffrey Shelton Okot , I am running into the same issue. We have a cluster in the prod (HA), and currently it is in 2.2.8 version. We are planning to upgrade it to 2.4. It was installed manually with salt, and now we want it to be managed with Ambari. The option 2 described by Geoffrey looks to be interesting. Would it be possible to provide more details on the APIs that should be invoked? Or if anyone could share his experience on this subject, it would be great. Thanks.
