Management traffic includes things such as communication between the Control Plane &lt;-&gt; Data Plane, etc</P><P></P> Fri, 25 Jun 2021 22:40:38 GMT https://community.databricks.com/t5/data-engineering/why-does-databricks-need-two-ip-addresses-per-node-in-a-cluster/m-p/18284#M12103 aladda 2021-06-25T22:40:38Z
