-
-  Apache Hadoop 0.23 consists of significant improvements over the previous 
-  stable release (hadoop-0.20.205).
-
-  Here is a short overview of the improvments to both HDFS and MapReduce.
-
-* {HDFS Federation}
-
-  In order to scale the name service horizontally, <federation> uses multiple 
-  independent Namenodes/Namespaces. The Namenodes are federated, that is, the 
-  Namenodes are independent and don't require coordination with each other. 
-  The datanodes are used as common storage for blocks by all the Namenodes. 
-  Each datanode registers with all the Namenodes in the cluster. Datanodes 
-  send periodic heartbeats and block reports and handles commands from the 
-  Namenodes.
-
-  More details are available in the {{{./Federation.html}HDFS Federation}}
-  document.
