Description

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 cannot be cast to java.lang.Long
