Oh yeah! The code did it :-D
For those that come after, I guess 'hbase shell' is broken for remote
access. Use the raw Java API
Many thanks again Mark!

1. Look in the logs;
2. I think hbase shell works only locally;
3. The code below worked for me, and I don't use a config file, but give
the params directly:
public void connect() throws IOException {
Configuration hConf = HBaseConfiguration.create();
hConf.set(MyConstants.HBASE_CONFIGURATION_ZOOKEEPER_QUORUM,
MyConstants.zookeeperUrl);
hConf.set(MyConstants..HBASE_CONFIGURATION_ZOOKEEPER_CLIENTPORT,
MyConstants.zookeeperPort);
String tableName = "MyTable";
HTable hTable = new HTable(hConf, tableName);
hTable.close();
}

Still no love... Any suggestions?
I'm on EC2, and I am trying to set up a Pseudo-Distributed HBaser Server
on one machine, and access it from another. Both machines are EC2.
I have already found the doc below, and I followed the instructions
http://hbase.apache.org/book.**html#client_dependencies<http://hbase.apache.org/book.html#client_dependencies>
My server is up and running, and I can access it from an 'hbase shell' on
the machine. The hbase-site.xml is ...
<configuration>
<property>
<name>hbase.zookeeper.quorum</**name>
<value>ip-XX-YYY-Z-QQQ.ec2.**internal</value>
</property>
<property>
<name>hbase.cluster.**distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost/hbase<**/value>
</property>
</configuration>
The client machine hbase-site.xml is...
<configuration>
<property>
<name>hbase.zookeeper.quorum</**name>
<value>ip-XX-YYY-Z-QQQ.ec2.**internal.ec2.internal</value>
<description>Pseudo Distributed Server</description>
</property>
</configuration>
And when I try 'hbase shell' remotely, I get this...
hbase(main):001:0> status 'detailed'
ERROR: org.apache.hadoop.hbase.**ZooKeeperConnectionException: HBase
is able to connect to ZooKeeper but the connection closes
immediately. This could be a sign that the server has too many
connections (30 is the default). Consider inspecting your ZK server
logs for that error and then make sure you are reusing
HBaseConfiguration as often as you can. See HTable's javadoc for
more information.
