> 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.
