Windows NFS client access secured HDFS as 'nobody'

Windows NFS client access secured HDFS as 'nobody'

Contributor

Hello

This is going to be a bit security question.

I've setup Secured Hadoop cluster using Kerberos. I also setup NFS Gateway using Cloudera Manager. I made sure firewalls are open and my IP is listed on NFS whitelist.

 

On Windows Client,

if I use "Map Network Drive" wizard, or even if I mount Hadoop NFS using Windows command line "mount <servername>:/! X:", NFS Gateway log shows that I'm accessing the HDFS as "nobody" user.

I do have proper Kerberos ticket from Windows AD using kinit command.

 

If I specify -o sec=krb5 option on the mount command, I get Access Denied error

 

mount -o sec=krb5 <servername>:/! X:

Access is Denied

 

On linux, I'm successfully able to kinit and mount NFS drive as my AD username.

 

Did anyone have similar issue?

 

Thank you 

Ben
