Description

The io.serialization property in core-default.xml has a very long value in a single line, as below

<property>
  <name>io.serializations</name>
  <value>org.apache.hadoop.io.serializer.WritableSerialization,org.apache.hadoop.io.serializer.avro.AvroSpecificSerialization,org.apache.hadoop.io.serializer.avro.AvroReflectSerialization</value>
  <description>A list of serialization classes that can be used for
  obtaining serializers and deserializers.</description>
</property>

which not only break the code style (a very long line) but also not fit well in browser. Due to this single very long line, the "description" column can not show in browser by default
