@Geoffrey Shelton Okot In that case why would it work fine for sometime before going down? Also if I comment out 127.0.0.1, the nifi server doesn't start at all.

Hi, I have a 3 node nifi cluster. I want to persist my flow file changes to a Git repo. I could do it locally on my single node system and it is very helpful in versioning. Wanted to check how will the configuration be done in the 3 node cluster. Can I just have registry on only one node in the cluster or should I put it in all 3 nodes. Also if such a thing is not supported, is there any work around to use nifi registry with a nifi cluster.
