failed to get job node pool %q: %v

Error message

failed to get job node pool %q: %v

What it means

SystemScheduler.setJob failed to look up the job's node pool in the state store. The scheduler needs the pool to apply the correct scheduler configuration; the wrapped error holds the store cause.

Solutions

1. Check server logs for the state store error
2. Verify the node pool still exists; the eval will be retried
