Offload Node

Although DC/OS NiFi supports the offload-node feature of NiFi, we do not recommend using this feature because DC/OS does not support scaling down.

WARNING: After offloading, even if you delete the node, it will not be removed from the cluster. If you run cluster view in the NiFi UI, the node will not be displayed, but it is still running and will consume DC/OS resources.

To offload a node:

1. Go to Cluster.

2. Disconnect node you want to offload:
