Li Lu commented on YARN-4224:

Oh and I forgot to mention one point. For each of the proposed end points, not 
providing an UID means querying them. Apps can be one example, flows can also 
be one example. One problem is that if there's no query parameter for those 
queries, there may be too many of them. So, we need to enforce some parameters 
to limit the number of entities returned from the calls.
