Sounds like you are reading the documentation for 0.20.6 but using the 0.89.x that is bundled with CDH? If so, the two are not aligned. You probably need this: http://hbase.apache.org/docs/r0.89.20100726/apidocs/overview-summary.html#overview_description For how to connect to remote server, you specify zookeeper ensemble. If you are running standalone, it'll find the in-process zookeeper instance w/o configuration. Otherwise you are into pseudo-distributed or distributed modes both of which are covered in the cited URL -- see where zookeeper ensemble is specified.
