Did you first create the table and then try to delete it? In hbase-0.1.1 and older, offlining a table did not work reliably. There is a fix for this problem in the hbase-0.1.2 release candidate.
Also, if you direct hbase questions to the hbase mailing list [email protected] you will get a more timely response.
