Notes about HA Name Node

Regards to all the list
I was reading the NoSQL Weekly, and I saw that the HDFS developers are 
working in one of the most requested features for HDFS: High 
Availability in the NameNode (HA Name Node). Where I can find more 
information about this development?

Best wishes

Cloudera CHD4 have this feature. They have released CDH4 Beta1, we can
evaluate on that. Hope the CDH4 production version will release in this
year.
