John Zhuge commented on HDFS-7499:
----------------------------------

Wonder whether we can add an HDFS based layout type for 
[pNFS|http://tools.ietf.org/html/rfc5661#section-12], similar to [Object-Based 
Parallel NFS (pNFS) Operations|http://tools.ietf.org/html/rfc5664]. The storage 
protocol can be a C/C++ based {{DFSClient}}.

> Add NFSv4 + Kerberos / client authentication support

>             Project: Hadoop HDFS
>          Issue Type: New Feature
>    Affects Versions: 2.4.0
>         Environment: HDP2.1
>            Reporter: Hari Sekhon
>
> We have a requirement for secure file share access to HDFS on a kerberized 
> cluster.
> This is spun off from HDFS-7488 where adding Kerberos to the front end client 
> was considered, I believe this would require NFSv4 support?
