Which map reduce library are you using?

Here's the scoop...
One of my first mapreduce jobs didn't want to complete by itself. It
did not want to abort either. To get rid of the sucker I deployed a
new application version and deleted the one the job was running
against. I also manually deleted all the residual state mapreduce
created in the datastore. That seemed to kill most of it. However now,
5 days later, there are still two artifacts - mapperCallback and
controllerCallback - that disturb my serenity (and keep sucking the
juice) by popping up every hour or so. Obviously they are looking for
a job that exists no more and fail miserably with a stack trace
similar to below.
Is there a way to make them go away?
