some details on jena-hadoop-rdf?

I'm looking to incorporate Jena into a MapReduce job and was curious as to
the status/stability of the jena-hadoop-rdf module. Is it ready for use?
If not, is there an expected time when it might be? I've looked at the
Jira project, but there doesn't seem to be an issue directly related to
"productizing" it.

Thanks,
Mike
