the existence of a namespace, which does not require ADMIN permissions

> Key: HBASE-22377
> URL: https://issues.apache.org/jira/browse/HBASE-22377
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 1.3.2
> Reporter: Chinmay Kulkarni
> Priority: Major
>
> 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.
