tooptoop4 commented on issue #36: [RANGER-2395] Add Presto plugin
URL: https://github.com/apache/ranger/pull/36#issuecomment-570348580
 
 
   some fixes:
   
   https://github.com/apache/ranger/blob/master/plugin-presto/src/main/java/org/apache/ranger/authorization/presto/authorizer/RangerSystemAccessControl.java#L130
change checkCanSetSystemSessionProperty to have a dummy IF condition that always results in
false so that session properties are never denied
   
   https://github.com/apache/ranger/blob/master/plugin-presto/src/main/java/org/apache/ranger/authorization/presto/authorizer/RangerSystemAccessControl.java#L130
change checkCanSetUser to have an IF condition (principal does not equal userName) then accessDenied.
This is critical so that users can't impersonate the privileges of another user
   
   https://github.com/prestodb/presto/issues/13394 remove deny in presto code
