HBase completebulkload returns exception - hadoop

Question

I am trying to bulk-populate an HBase table quickly from a text file (several GB) by using the bulk loading method described in the Hadoop docs.
I have created an HFile which I now want to push to my HBase table.
When I use this command:
hadoop jar /home/hxcaine/hadoop/lib/hbase.jar completebulkload /user/hxcaine/dbpopulate/output/cf1 my_hbase_table
The job starts and then I get this exception:
Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/util/concurrent/ThreadFactoryBuilder

However, I can see that the Guava jar is in my classpath and when I check inside the jar I can see ThreadFactoryBuilder.class.
I am using these versions (and stuck with them):
Hadoop 0.20.2-cdh3u3
HBase 0.90.4-cdh3u3
Guava jar: /usr/lib/hadoop-0.20/lib/guava-r09-jarjar.jar
I do have an older Guava jar in my classpath but I don't know where it came from, I don't suppose it should have an effect.
Any ideas?

what happens if you run:
export HADOOP_CLASSPATH=`hbase classpath`
before running the load? From the stack trace, it looks like the jar is needed by one of the actual tasks though I am surprised to see that this actually kicks off an M/R job.
