> We need to be able to use hadoop over hostile networks, both internally and
> externally to the enterpise. While authentication prevents unauthorized
> access, encryption should be used to prevent such things as packet snooping
> across the wire. This means that hadoop client connections, distcp, etc,
> would use something such as SSL to protect the TCP/IP packets.
> Post-Kerberos, it would be useful to use something similar to NFS's krb5p
> option.
