      Description

      The Hadoop NameNode is a single point of failure. If the master instance fails, HDFS is down; therefore, HBase as well. So we do not try to deploy HBase in a multimaster configuration for that reason. Instead we colocate the HDFS NameNode and HBase HMaster on the same instance and run with its failure as a known risk. As these EC2 scripts are starter scripts which can (and should) be customized, this is ok, but we can do better. We should deploy a fully fault tolerant Hadoop+HBase cluster as a worked example of how to do it.
