In addition configuring the right cluster configurations was not easy. I used a separate zookeeper instance which runs on one node and others connect to that first node. A NiFi nifi. In the future, we hope to provide supplemental documentation that covers the NiFi Scaling number of NiFi nodes. protocol. Have used the following environment variables for Nifi: version: '3.

I'm using the following configs to create the two nodes cluster: For the First node The nifi. shasum -a 256 Each node in a NiFi cluster needs a hostname (e. When clustered, a property for each node should be defined, so that every node knows about every other node. address - Set this to the fully qualified hostname of the node. address needs to be updated with the name used for the current node within the /etc/hosts file.
