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.
