Rong Rong created FLINK-15561:
---------------------------------

             Summary: Improve Kerberos delegation token login 
                 Key: FLINK-15561
                 URL: https://issues.apache.org/jira/browse/FLINK-15561
             Project: Flink
          Issue Type: Bug
          Components: Deployment / YARN
            Reporter: Rong Rong
            Assignee: Rong Rong


Currently the security HadoopModule handles delegation token login without spawning a delegation token renewal thread. We might need to include this to support delegation token.
