Hi @eniwoke 

Thank you for replying!
I have one job that has a string of other jobs and notebooks as tasks.  This job is designed to be run against different tenants as a way of ingesting data.

NB1 at the beginning of the job determines the t-shirt size for the tenant and if it's S, all subsequent tasks and jobs need to run on the S cluster.  If NB1 finds the t-shirt size is M, all following tasks and jobs will run on the M cluster.
At the moment, I can only set one cluster per task and can't see a way of dynamically setting the cluster to use based on the output of a previous task.
Hope this clarifies the ask a little bit!

Thanks!
