Hi 

I have successfully setup Drill-on-YARN along side with my hadoop cluster. Now, I enabled HTTP drill security by using PAM authentication method. 
My problem is, every time i tried to login using SSH accounts, it's always giving me `invalid user name or password` while using the correct credentials. 

Also filed ticket for this... https://issues.apache.org/jira/browse/DRILL-6983

Best regards,
