I would like to have about 10 nodes running quartz and have 2 of them do a large number of small tasks and have 8 of them do another specific set of large tasks, scheduled by the "small task" machines. Is this possible from within a single cluster?

This is something that's on our roadmap but doesn't exist yet. Stay tuned and jump into the process even if it's just reviewing what we are planning and adding your feedback.

Actually, it's possible now, just not elegantly.

Node-specific features don't currently exist, though they are on the road map.

For now, you'll have to use two instances of Quartz per node. --- Essentially configuring two clusters.

One cluster of schedulers will exist on all nodes, but only have start() invoked on the scheduler on 2 nodes.

The other cluster of schedulers will exist on all nodes, but only have start() invoked on 8 nodes.

Jobs running on either node should be able to use either scheduler (whether start()ed or no) to schedule jobs.

Only the nodes that have start() called on them will execute jobs.
