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?
