[jira] [Created] (HBASE-22377) Provide HBaseAdmin API to check the existence of a namespace, which does not require ADMIN permissions

Chinmay Kulkarni created HBASE-22377:
----------------------------------------

             Summary: Provide HBaseAdmin API to check 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


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.
