Subject Re: Storm Slots - creating and deploying parsers

That’s a great idea, at the moment I believe it just sort of fails silently when creating
the topology, so we should definitely get a JIRA for that. I’ll kick off something to collect
some of the collected wisdom from everyone as well I think on Storm, maybe we need a tuning
page similar to Jon’s excellent Search tuning page.

tend to just add a bunch of ports at install, and create slots across the supervisors, but
you can always add more supervisors too.
