For what it's worth, I deploy HBase jars into the Hadoop library directory so I don't have
to deal with this. Way back I had classpath problems with 'hadoop jar', and not just with
HBase. That may not be a satisfactory answer, but it works for me.

I made an executable jar with all the jars in a lib folder with each listed
in the MANIFEST file under Class-Path.   Looks like this:

Manifest-Version: 1.0
Class-Path: lib/ojdbc14.jar  lib/commons-cli-2.0-SNAPSHOT.jar lib/comm
ons-httpclient-3.0.1.jar  lib/commons-loggin-1.0.4.jar  lib/commons-l
ogging-api-1.0.4.jar  lib/commons-math-1.1.jar  lib/jetty-5.1.4.jar  
lib/jruby-complete-1.1.6.jar  lib/junit-3.8.1.jar  lib/libthrift-2008
0411p1.jar  lib/log4j-1.2.13.jar  lib/lucene-core-2.2.0.jar  lib/serv
let-api.jar  lib/xmlenc-0.52.jar  lib/zookeeper-3.0.1.jar lib lib/had
oop-0.19.1-core.jar  lib/hadoop-0.19.1-test.jar lib/hbase-0.19.3.jar 
  lib/hbase-0.19.3-test.jar 
Main-Class: com.techsys.hbase.test.ColumnCountMapReduce

then i ran the executable from like this:

hadoop19/bin/hadoop jar dev/columncounter/columncounter.jar inputTableName

Errors:
