Illegal Access error

[Mark Snow <ma...@yahoo.com>]

I'm running hbase0.2.0/hadoop0.17.0 with a simple script to create a table, then fill it with data. The create table part isn't a MR job, but run from the hadoop jar. (I used the Gradestable example from the list about a month ago as a template)

I get the following error with the create table call:

I'm guessing you are bundling hbase jar up in your job jar?  If so, from 
http://wiki.apache.org/hadoop/Hbase/MapReduce, "NOTE: While previous it 
used to be possible to bundle the hbase.jar up inside the job jar you 
submit to hadoop, as of 0.2.0RC2, this is no longer so. See HBASE-797. 
"  See just above this note for how to add hbase jar to the 
HADOOP_CLASSPATH on your cluster.
