Hi Todd,
What user are you using to start the nfsgateway service? Basically in the example where the following property is set:
hadoop.proxyuser.nfsserver.groups
The nfsserver is the user starting the gateway. Hence if you use let’s say user todd, the property would be hadoop.proxyuser.todd.groups
and hadoop.proxyuser.todd.hosts
I hope that helps.
Regards,
Robert
