org.apache.hadoop.conf.Configured

oracle.spatial.hadoop.vector.mapred.job.BaseJob<K,V>

oracle.spatial.hadoop.vector.mapred.job.IndexedInputBaseJob<K,V>

oracle.spatial.hadoop.vector.mapred.job.Categorization<K,V>

oracle.spatial.hadoop.vector.mapreduce.job.Categorization<K,V>

Type Parameters:

K - the type of the input keys

V - the type of the input values

All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, org.apache.hadoop.util.Tool

public class Categorization<K,V>
extends Categorization<K,V>

This class can be used to run or configure a job for categorizing records of an input dataset into features of a hierarchical dataset.

The result will be a summary file for each hierarchical level containing the number of records from the non-hierarchical dataset per hierarchy level feature.

The categorization can be performed determining a spatial interaction specified by a spatial operation or using MVSuggest.
