             Summary: Support cluster provisioning when using Flink on Dataproc
                 Key: BEAM-14449
                 URL: https://issues.apache.org/jira/browse/BEAM-14449
             Project: Beam
          Issue Type: Improvement
          Components: runner-py-interactive
            Reporter: Ning
            Assignee: Ning


Provide the capability for the user to explicitly provision a cluster.

Current implementation provisions each cluster at the location specified by 
GoogleCloudOptions using 3 worker nodes. There is no explicit API to configure 
the number or shape of workers.

We could use the WorkerOptions to allow customers to explicitly provision a 
cluster and expose an explicit API (with UX in notebook extension) for 
customers to change the size of a cluster connected with their notebook (until 
we have an auto scaling solution with Dataproc for Flink).
