--------------------------------------

             Summary: TableMapReduceUtil.initTableMapperJob unnecessarily 
limits the types of outputKeyClass and outputValueClass
                 Key: HBASE-12929
                 URL: https://issues.apache.org/jira/browse/HBASE-12929
             Project: HBase
          Issue Type: Improvement
          Components: mapreduce
            Reporter: Will Temperley
            Priority: Minor


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
