Programtically invoking a Map/Reduce job

[Mike Hugo]

I'm writing a client program that uses the BatchWriter and BatchScanner for
inserting and querying data, but occasionally it also needs to be able to
kick of a Map/Reduce job on a remote accumulo cluster.  The Map/Reduce
examples that ship with Accumulo look like they are meant to be invoked via
the command line.  Does anyone have an example of how to kick something off
via a java client running on a separate server?  Any best practices to
share?
Thanks,
Mike
