AccumuloInputFormat and non-Text Keys

All,
I went to write some map/reduce code today that will use the AccumuloInputFormat to add records to Accumulo.  However, when I went to build my Mutation object, it quickly became apparent that Mutation only supports character based keys (Text and CharSequence).  Is there any way to write records to Accumulo in Map Reduce when column qualifiers or column families are binary data rather than char data?

Thanks,
Tejay

Text is just a wrapper for a byte array.  You can put binary data in a Text.
