David, Thanks for the information. I've issued those two commands in my hadoop shell and still get the same error when I try to initialize accumulo in *its* shell. :
2015-03-02 13:30:41,175 [init.Initialize] FATAL: Failed to initialize filesystem org.apache.hadoop.security.AccessControlException: Permission denied: user=accumulo, access=WRITE, inode="/accumulo": accumulo.supergroup:supergroup:drwxr-xr-x My comment that I had 3 users was meant in a linux sense, not in a hadoop sense. So (to borrow terminoloy from RDF or XML) is there something I have to do in my hadoop setup (running under linix:hadoop) or my accumulo setup (running under linux:accumulo) so that the accumuulo I/O gets processed as from someone in the hadoop:supergroup? I tried running the accumulo init from the linux:hadoop user and it worked. I'm not sure if any permissions/etc were hosed by doing it there. I'll see. Thanks for you help. (By the way, is it wrong or a bad idea to split the work into three linux:users, or should it all be done in one linux:user space?)
