Add the ZooKeeper Service
If you are running NiFi in a clustered environment, you must install ZooKeeper before adding the NiFi service. To add ZooKeeper, navigate to the Add Service page for your cluster and select ZooKeeper.
- From Home > Status tab, select the drop-down to the right of your cluster, and select Add a Service.
- Select ZooKeeper, and click Continue.
- Select the cluster nodes onto which you want to install ZooKeeper. Do not install ZooKeeper onto the same cluster node as NiFi.
