Abstract
The HDInsight name node is just another virtual machine provisioned in Windows Azure. Theoretically, this is the equivalent of the traditional Apache Hadoop name node or the head node, which is the heart and soul of your Hadoop cluster. I would like to re-iterate what I pointed out in Chapter 1: the name node is the single point of failure in a Hadoop cluster. Most important of all, the name node contains the metadata of the entire cluster storage blocks and maintains co-ordination among the data nodes, so understandably it could bring down the entire cluster.
