Reduce EBS Default Volumes

pabloanzorenac

By default Databricks creates 2 volumes: one with 30GB and the other one with 150GB. 
We have a lot of nodes in our pools and so a los of Terabytes of Volumes, but we are not making any use of them in the jobs. Is there any way to reduce the volumes? I couldn't found any documentation for reducing the default ebs volumes.
Thanks

I don't think you'll be able to do that. Clusters are pre-defined and there's no way to change a configuration of each machine.

However even if you think that you're not using them in the jobs, Spark may actually do benefit by using them (ex. for caching).

Yes, EBS vols are essential for shuffle spill for example. You are probably using them!
