Deploying a custom processor to a NiFi cluster

[#1]

Once creating a custom processor (described here) - what is the best way to deploy the nar file in a NiFi cluster? Do I need to deploy to every node in the cluster and then restart one at a time (rolling restart)? Did anything change with deploying a custom processor to the cluster with NiFi v1.0?

What you described is the correct process, the NAR needs to be copied to the lib directory on each node of the cluster, and then the nodes need to be restarted. Nothing has changed in 1.0.0 that changes this approach.
