Subject [jira] [Commented] (HDFS-9568) Support NFSv4 interface to HDFS
Date Wed, 16 Dec 2015 23:20:46 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9568?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15061103#comment-15061103
] 

John Zhuge commented on HDFS-9568:
----------------------------------

[NFSv4|https://tools.ietf.org/html/rfc7530] added a new security flavor [RPCSEC_GSS|https://tools.ietf.org/html/rfc5403]
which uses [GSS-API|https://tools.ietf.org/html/rfc2743] to supports multiple mechanisms that
provide security services. "For interoperability, NFSv4 clients and servers MUST support the
Kerberos V5 security mechanism." (a quote from [NFSv4 spec section 3.2.1|https://tools.ietf.org/html/rfc7530#section-3.2.1])

With that, I think [HDFS-7499|https://issues.apache.org/jira/browse/HDFS-7499] is dependent
on a sub-task (Add RPCSEC_GSS support) of this umbrella jira. What do you think?

> [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.
