> Along the same lines as ACCUMULO-2464, the MapReduce AuthenticationToken serialization also has the potential to be stored in a non-secure form. Some of this is mitigated via Base64 the password to remove human-readable-ness, the ability to serialize an AuthenticationToken to a file, etc.
> Wiring up a CredentialProvider as an AuthenticationToken is another option provided to us by Hadoop likely to handle tricky security-related concerns for us.
