> I suppose the issue is in line:
> this.forwardObj [ i ] = res.convertIfNecessary(rowList.get( i ),
> f.getFieldObjectInspector());
> there is never reason for conversion, it should just be:
> this.forwardObj [ i ] = rowList.get( i )
> Caused by: java.lang.ClassCastException: org.apache.hadoop.io.LongWritable
