Sergio Peña commented on SENTRY-2154:
-------------------------------------

I see the same circular dependency with roles and dependencies

privileges->roles->privileges
{noformat}
MSentryPrivilege {
  Set<MSentryRole> roles;
}

MSentryRole {
  Set<MSentryPrivilege> privileges;
  Set<MSentryUser> users;
}{noformat}
How does DN work differently between these two JDO objects? 

privileges->roles->users->privileges?
{noformat}
MSentryPrivilege {
  Set<MSentryRole> roles;
}

MSentryRole {
  Set<MSentryPrivilege> privileges;
  Set<MSentryUser> users;
}

MSentryUser {
  Set<MSentryPrivilege> privileges;
  Set<MSentryRole> roles;
}{noformat}

> Need to add new DB table to support grant user to privileges
> Also, a flag should be added in privilege table to indicate the privilege is 
> created by user, or created by sentry implicitly. User can view the implicit 
> privileges, but cannot change it directly
