oracle.hadoop.balancer.examples.invindx.InvertedIndex.InvertedIndexKey.WordPartitioner<V>
- All Implemented Interfaces:
- org.apache.hadoop.mapred.JobConfigurable, org.apache.hadoop.mapred.Partitioner<InvertedIndex.InvertedIndexKey,V>
- Enclosing class:
- InvertedIndex.InvertedIndexKey
-
public static class InvertedIndex.InvertedIndexKey.WordPartitioner<V>
- extends org.apache.hadoop.mapreduce.Partitioner<InvertedIndex.InvertedIndexKey,V>
- implements org.apache.hadoop.mapred.Partitioner<InvertedIndex.InvertedIndexKey,V>
Partition on the word's hashcode. This class extends org.apache.hadoop.mapreduce.Partitioner and implements org.apache.hadoop.mapred.Partitioner, so it can be used by both mapred and mapreduce versions of Inverted Index
