> The initTableMapperJob methods in TableMapReduceUtil which take multiple scans unnecessarily
limit the types of the outputKeyClass and outputValueClass parameters, requiring them to extend
WritableComparable and Writable respectively.  
> In my specific use case, therefore, I cannot create a mapper job which outputs an hbase.client.Result.
> The methods in the MapReduce API to set map output key and value types do not impose
this restriction.
> The other overloads of initTableMapperJob do not have this limitation - the restrictions
were removed by https://issues.apache.org/jira/browse/HBASE-7024
