> Currently, to check the existence of a namespace, clients can use 
> HBaseAdmin#getNamespaceDescriptor. eEventually on the server-side, this calls 
> AccessController#preGetNamespaceDescriptor which tries to acquire ADMIN 
> permissions for that namespace.
> We should have an API for clients to be able to check the existence of a 
> namespace, without necessarily obtaining the namespace descriptor. Such an 
> API would not require ADMIN permissions.
