One node Apache NiFi cluster

I am setting up a secure cluster with NiFi 1.7.1 using an external Zookeeper

While I do plan to have 3 nodes in the cluster, at the moment I am only going to start one node. Is that a valid cluster from NiFi standpoint.

The reason for my question is I get this SSL Handshake error during startup and I want to rule out that having single not is not the cause of this problem,

Thanks

Vijay

Without seeing your SSL handshake error, please be aware that Apache NiFi 1.7.1 enforces RFC 6125 so certificates need a valid SubjectAlternateName entry in order for validation to occur. If you generated the certificate using the NiFi TLS Toolkit (v 1.7.1+) you should be ok, but a legacy certificate with only a DN entry will fail. - Andy

Yes, a single node can be run as a cluster.
