The NFS-gateway uses proxy user to proxy all the users accessing the NFS
mounts.
In non-secure mode, the user running the gateway is the proxy user, while
in secure mode the
user in Kerberos keytab is the proxy user. Suppose the proxy user is
'nfsserver'
- and users belonging to the groups 'users-group1'
- and 'users-group2' use the NFS mounts, then in core-site.xml of the
NameNode, the following

the following
two properities must be set and only NameNode needs restart after the
configuration change
(NOTE: replace the string 'nfsserver' with the proxy user name in your
cluster):

<description>
- The 'nfsserver' user is allowed to proxy all members of the
'users-group1' and
- 'users-group2' groups. Note that in most cases you will need to
include the
- group "root" because the user "root" (which usually belonges to
"root" group) will
- generally be the user that initially executes the mount on the NFS
client system.
- Set this to '*' to allow nfsserver user to proxy any group.
