How to import issues but not users into Jira?

Question

How can I import issues but not users into Jira?

I have a Bugzilla database.  I've successfully exported from Bugzilla to a local Jira instance and then into Jira OnDemand.  That said, when I went through the process a second time, there was no option to exclude the user import into either Jira local instance or Jira OnDemand.  This is an issue because we've already got the users set the way we want them in the production Jira OnDemand.  So how can we import the issues but not the users?  Or is there a way to get the users to intelligently import instead of blowing away the existing user data?

Well, while importing issues the importer needs to do something with reporter, assignee (and other of type user) fields and the author of comments, worklogs, etc.

So it either has to create corresponding users for these entities (you don't want them to be "undefined") or, if you already have users in your JIRA instance, you have to use the appropriate user mapping.

You can specify it via importer wizard. If you have tons of users then, I would suggest mapping just a handful via UI and, saving configuration file and then editing it - it will be more effective than using web UI which is not designed to deal with mass-mapping.
