Can multiple GCP Dataproc clusters use same metastore?

Question

Planning to use Dataproc cluster with Dataproc Metastore.

Questions:

• when we delete Dataproc clusters, would Dataproc Metastore continue to remain available?
• Can two different Dataproc clusters in same region, use same Dataproc Metastore?
• Can two different Dataproc clusters on different region, use same Dataproc Metastore?

As what Dagang said, the answer is to use an external metastore that persists outside of the cluster lifecycle. You can do this in two ways:

Using Dataproc Metastore Service

Using Cloud SQL proxy
