One thing I've noticed is that my client stack trace makes no mention of using an SASL transport (It's the last log dump in this email). Maybe this is the problem; Accumulo wants an SASL connection, but for some reason the client app isn't using an SASL transport even though I'm using a Kerberos Token?
