I think we can keep apis in GetQueueUserAclsInfoRequest as Unstable. Or were there any other
discussion on same?
{quote}
Currently is stable and the way i understand about stable and unstable we can keep it same
{code}
Stable
   * Can evolve while retaining compatibility for minor release boundaries.; 
   * can break compatibility only at major release (ie. at m.0).
Unstable
   * No guarantee is provided as to reliability or stability across any
   * level of release granularity.
{code}

If we use an old client List<String> queueNames = request.getQueueNames(); could come
as NULL. ref ClientRMService#getQueueUserAcls
{quote}
IIUC repeated the default value should be EMPTY list .
{code}
    private void initFields() {
      queueNames_ = com.google.protobuf.LazyStringArrayList.EMPTY;
      userName_ = "";
    }
{code}

All other comments are handled.

> Currently {{ApplicationClientProtocol#getQueueUserAcls}} return data for all the queues
available in scheduler for user.
> User wants to know whether he has rights of a particular queue only. For systems with
5K queues returning all queues list is not efficient.
> Suggested change: support additional parameters *userName and queueName* as optional.
Admin user should be able to query other users ACL for a particular queueName.
