Package org.apache.hadoop.io.serializer

package org.apache.hadoop.io.serializer

This package provides a mechanism for using different serialization frameworks in Hadoop. The property "io.serializations" defines a list of Serializations that know how to create Serializers and Deserializers.

To add a new serialization framework write an implementation of Serialization and add its name to the "io.serializations" property.
