Only these two - or you don't really care about permissions ?

If I guess right that you want to restrict access to super-user and
two other users alone, but not all users, there's probably no easy way
out other than creating a new group with those two users and giving
that group permissions. HDFS permissions aren't fine-grained like ACLs
which can grant access to specific users irrespective of their group
