I don't think there is anyone except Facebook actually uses it. Their
case is special, as they have millions and millions of files in HDFS.

Hi All,

I am running the HBase distributed mode in seven node cluster with backup master. The HBase is running properly in the backup master environment. I want to run this HBase on top of the High Availability Hadoop. I saw about Avatar node in the following link http://hadoopblog.blogspot.com/2010/02/hadoop-namenode-high-availability.html .
I need more help regarding this Avatar namenode configuration.


1. Which IP will be given to the Datanoe fs.default.name ?
2. Is there any good method other than avatar available for Backup namenode ?



Regards,

Shanmuganathan
