Class HiveKey

java.lang.Object
  org.apache.hadoop.io.BinaryComparable
      org.apache.hadoop.io.BytesWritable
          org.apache.hadoop.hive.ql.io.HiveKey

All Implemented Interfaces:

public class HiveKey
extends org.apache.hadoop.io.BytesWritable

HiveKey is a simple wrapper on Text which allows us to set the hashCode easily. hashCode is used for hadoop partitioner.
