Last Updated: Jun 10, 2020

If a virtual cluster is in the RUNNING state, you can use the virtual cluster to submit Spark jobs. If you do not want to submit Spark jobs by using a specific virtual cluster, you can stop the virtual cluster. Then, the virtual cluster is in the STOPPED state.

If a virtual cluster is in the STOPPED state, you cannot use the virtual cluster to submit Spark jobs. Then, you can start or delete the virtual cluster.
