Subject Re: Programtically invoking a Map/Reduce job
Date Wed, 16 Jan 2013 17:20:35 GMT
The code examples we have scripted simply do the necessary setup for
creating a mapreduce job and kicking it off. If you check out the code for
them in
you can see what we're doing in Java to kick off jobs.

The short explanation is, just like any other MapReduce job, we're setting
up a Job, configuring the AccumuloInput and/or OutputFormats, and sending
them off like any other MapReduce job.
