Hi all, In trying out different settings for performance, I run into a job failure case that puzzles me.
I’d done a run with a parallelism of 20 (-p 20 via CLI), and the job ran successfully, on a cluster with 40 slots. I then tried with -p 15, and it failed with: NoResourceAvailableException: Not enough free slots available to run the job. You can decrease the operator parallelism… But the change was to reduce parallelism - why would that now cause this problem?
