Thank you for the clarification. That's exactly what I mean. I'm not using autoscaling since I've been submitting a job to run with a required number of worker nodes. From my observation, even when some workers are not ready, the cluster will begin once it has a decent number of worker nodes. The description shown from databricks is 'Some nodes are taking much longer to become ready than others, and have been skipped in order to unblock cluster launch'. And my issue I would need to make sure all worker nodes are ready and then run the code.
