Subject [jira] Commented: (HADOOP-2239) Security: Need to be able to encrypt Hadoop socket connections
Date Thu, 14 Feb 2008 19:03:08 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2239?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12569044#action_12569044
] 

Doug Cutting commented on HADOOP-2239:
--------------------------------------

> should it be "hftps:" rather than "hsftp:"?

Whatever.  Both SFTP and FTPS refer to secure file-transfer protocols.  The former does not
require certs, while the latter (like HTTPS) does.  So maybe FTPS is a better analogy, but
HSFTP reads better to me, as the Hadoop Secure File Transfer Protocol.

> 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.
