Quicker cluster startup times
Currently it takes nearly 7 minutes to provision a cluster. This creates problems when running jobs that need to run fairly frequently. Workarounds include using an existing cluster but the recommended approach when creating a job is to create a new cluster for each job run.
Agreed, though we can consider playing around with idle time before cluster is terminated - but this will not provide good balance with cost and availability. Provide options to influencing cluster start time.
