java.lang.Object
org.apache.hadoop.mapred.MapReduceBase
com.intel.hadoop.graphbuilder.preprocess.mapreduce.EdgeTransformReducer<VidType>
- Type Parameters:
VidType
-
- All Implemented Interfaces:
- java.io.Closeable, org.apache.hadoop.mapred.JobConfigurable, org.apache.hadoop.mapred.Reducer<VidType,PairListType,org.apache.hadoop.io.Text,org.apache.hadoop.io.Text>
public class EdgeTransformReducer<VidType extends org.apache.hadoop.io.WritableComparable<VidType>>
- extends org.apache.hadoop.mapred.MapReduceBase
- implements org.apache.hadoop.mapred.Reducer<VidType,PairListType,org.apache.hadoop.io.Text,org.apache.hadoop.io.Text>
The Reduce functional computes a sufficient statistics on a list of edges,
and the Apply functional applies it back to each edge in the list.
