Subject Re: Hadoop 2.0 High Availability and Federation
Date Wed, 25 Jul 2012 03:32:22 GMT
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>
*  .

Wish this will help you.
