Is it impossible to move or add JournalNode by Ambari?

[#1]

A host that JournalNode is assigned went down by hardware trouble. So I want to move that JournalNode to another host. However, I can't find the way how to move or add JournalNode by Ambari. Is it impossible to move or add JournalNode by Ambari?

Is using Ambari REST API the only way for it? I found some articles using Ambari REST API for this problem.

I recently moved a journal node from one cluster machine to another by following procedure given here:

https://community.hortonworks.com/questions/4272/process-for-moving-hdp-services-manually.html

and informing Ambari about adding the 4th JN, and then deleting the one I wanted to move. It's similar to the article you found but a little bit simpler. The Ambari API calls are given in the article you found.
