I believe the mapreduce API is the newer one.

Hi there, I have a use case where I need to use a Chain Mapper and/or
Reducer. The problem is that
the AccumuloInputFormat extends hadoop.mapreduce.InputFormat rather than
implementing hadoop.mapred.InputFormat

Trying to make use of *org.apache.hadoop.mapred.lib.ChainMapper*
does not work because it requires the use of the mapred package. Is there a
version of the AccumuloInputFormat which uses
the hadoop.mapred package instead? Can InputFormatBase be rewritten with
the newer API?
