Chris Douglas updated HADOOP-2239:

    Attachment: 2239-0.patch

This roughly follows what Doug outlined above. I added a SunJsseListener to the namenode and
datanode StatusHttpServer, initialized iff the keystore location is specified. The keystore
properties- including passwords- are specified in another resource, specified in the config.
I added HsftpFileSystem to handle the client-side and included a redirect to a ssl-capable
datanode port from the NameNode servlet, assumed to be static (avoiding the protocol version

> 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.
