Allen Wittenauer commented on HADOOP-2239:
------------------------------------------
While we really need secure distcp Right Now(tm), it would be good if in the
future we could encrypt dfs put/get. I'm not so concerned about connectivity
between grid nodes (at least right now).
I suspect this JIRA needs to get broken down into multiple subtasks.
> Security: Need to be able to encrypt Hadoop socket connections

> Key: HADOOP-2239
> URL: https://issues.apache.org/jira/browse/HADOOP-2239
> Project: Hadoop Core
> Issue Type: Bug
> Components: dfs
> Reporter: Allen Wittenauer
>
> 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.
