Partially Resolved...
 
Taking your advise (both Jonathan and Aaron's) I was able to track the problem down.  The issue was that running insert (also batch_mutate) and using a consistencylevel of quorum on a cluster of 1 server with a replication factor of 1 does not work.  Well, that is not accurate, let me explain.  I believe the problem lies in the description of QUORUM as defined in the API on the wiki "Ensure that the write has been written to N / 2 + 1 replicas before responding to the client." 
 
1/2+1 = 1.5 -- One server can never accomplish this.  I believe I read something about this somewhere in all the documentation, but it would be really handy to have received an error telling me that it was impossible (assuming this was actually the issue).  I am by far, not familiar with the replication model, but if it is not by design, someone let me know and I'll report it.

Jonathan,
 
I have done it successfully with insert, but I have not tried it with mutate.  I'll give that a try tonight.
 
Thanks

I would try to get a single hard-coded column to insert, before doing
something more complex.

You can also enable debug logging on the server and see if that
matches what you want the client to be doing.
