Hi, Pardon me for asking such a stupid question.
I recently read an article about HBase basic architecture here: http://www.larsgeorge.com/2009/10/hbase-architecture-101-storage.html What really makes me wonder is, what if HBase is installed on machines where there is no HDFS? For example, there are ten linux machines (linux01, linux02, ... linux10), on which Hadoop 0.20.2 is installed, linux01 being Namenode and Jobtracker. Now, suppose that I install HBase on new computers linux11, linux12, linux13. Linux11 is the master and the rest are regionservers (Let's forget about zookeepers for argument's sake). If I configure hbase-site.xml so that hbase.rootdir would point to linux01, would this Hbase work properly? According to the article above, Hbase seems to have DFS clients of its own. So I thought HDFS and RegionServers could be separated. Am I right on this? Regards, Ed
