It's available at Hadoop 2.0. HDFS Federation supplied multiple Namespaces for the whole storage pool. The High Availability is specific for each Namespace/NameNode, so you can configure HA for each NameNode in the federation. You can get some document from https://ccp.cloudera.com/display/DOC/Documentation, especially the *CDH4 High Availability Guide<https://ccp.cloudera.com/download/attachments/18786211/CDH4_High_Availability_Guide_4.0.pdf?version=1&modificationDate=1340988760000> * .
