             Summary: Cache Kerberos tickets for long lived Daemons
                 Key: STORM-2214
                 URL: https://issues.apache.org/jira/browse/STORM-2214
             Project: Apache Storm
          Issue Type: Improvement
          Components: storm-core
            Reporter: Robert Joseph Evans
            Assignee: Robert Joseph Evans


The UI and supervisors authenticate to nimbus through kerberos.  But they initiate a new connection each time they do so, and even use a new Subject for each connection.  This means that the client must fetch a new service ticket each time and adds a lot of load on the KDC.

In order to reuse the subject between sessions we propose cacheing the Login instead of creating a new one each time.
