Clearing mapreduce generated records.

[D X]

I've run a lot of small mapreduce jobs and I realized I have a lot of old records on my /mapreduce/status page.

Is there a clean programatic way of clearing them out easily?

If you are sure all the jobs are complete, you can simply delete all the MapReduceState entity objects from the datastore. You can do this programatically, or use the admin UI.
