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?

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.

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