How do I make custom serialization code available on a cluster?

I am working with some data that has a custom IO serialization. So I've
added the appropriate class to the io.serializations property of
mapred-site.xml.

<property>
  <name>io.serializations</name>
<value>com.intelius.avroidm.Serialization,org.apache.hadoop.io.serializer.WritableSerialization</value>
</property>
