Subject [jira] [Commented] (HDFS-9568) Support NFSv4 interface to HDFS
Date Thu, 17 Dec 2015 00:03:46 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9568?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15061173#comment-15061173
] 

Allen Wittenauer commented on HDFS-9568:
----------------------------------------

(As a sidenote, I find this hilarious:

The previously required LIPKEY and SPKM-3 security mechanisms have been removed.

I seem to recall the story behind these requirements was that they were intended for non-Kerberized
environments. But the reality was that no one ever implemented them because the places that
cared already had Kerberos deployed.  There might have been a 'play' implementation of LIPKEY
internally, but I don't think it ever saw the light of day.  Which means that, officially,
no one ever really qualified as being fully RFC3530 compliant, including Sun!)

> [HDFS-4750|https://issues.apache.org/jira/browse/HDFS-4750] added NFSv3 interface to
HDFS. As NFSv4 client support in many OSes has matured, we can addd NFSv4 interface to HDFS.
There are some NFSv4 features quite suitable in Hadoop's distributed environment in addition
to simplified configuration and added security.
> This JIRA is to track NFSv4 support to access HDFS.
> We will upload the design doc and then the initial implementation.
