I haven't tried in a while but as far as I know you must run a
fully-distributed operation to be able to connect from "outside".

After that the steps are "fairly" easy. You have to include the hbase
jar along with all its dependencies (I know those aren't documented
anywhere right now: zookeeper, hadoop-core, hadoop-hdfs,
hadoop-mapred(?), commons-logging, commons-logging-api, log4j) and you
need a hbase-site.xml in your classpath that includes the property "
hbase.zookeeper.quorum" which needs to point to your zookeeper quorum
(in a single node testcase this would be only a single name/ip
address). I'm sure the XML file isn't necessary and a Configuration
object can be build manually...

After that it should work. I'm developing mainly on Windows too and it
works just fine. Building HBase etc. works too, only the tests won't
run.

There are improvements planned to refactor out a client jar that can
be easily used. Feel free to contact me if you need further help with
accessing HBase from Windows.

Cheers,
Lars
