Ok. Classpath looks good.
Few points: - org.apache.hadoop.hbase.client.Scanner doesn't exist for 0.94.6. - org.apache.hadoop.hbase.io.BatchUpdate doesn't exist for 0.94.6. - org.apache.hadoop.hbase.io.Cell doesn't exist for 0.94.6. - etc. http://hbase.apache.org/0.94/apidocs/index.html You might want to review you source code.
