Heh, ok.
I'm currently working through a bit of a prototype to see how it works.
I'm not a mapred/mapreduce expert, but I *think* I have an approach that
will work. Keep an eye out for a Jira -- would love feedback.

I recently looked into that and came to the same realization.
I ended up writing a new input format that did the cartesian product of two
tables. But to do that I had to store values for the left configuration
and right configuration and then copy over whichever config settings I
wanted to use for the AIF depending on which split i needed in the
RecordReader.
It would have been awesome if I could have just used the MultipleInputs ...

In executing some MapReduce over Accumulo with the AccumuloInputFormat, I
came to the realization that AIF fundamentally doesn't work with concepts
like MultipleInputs in Hadoop (http://hadoop.apache.org/
docs/current/api/org/apache/hadoop/mapreduce/lib/input/MultipleInputs.html).
Given that you can only write one set of configuration for AIF into a
Configuration object, there's not a mechanism to support multiple. This
appears to be the case across all versions.
Is this correct? Have I overlooked something?
