Robert Kanter created HDFS-4951:
-----------------------------------

             Summary: FsShell commands using secure httpfs throw exceptions due to missing
TokenRenewer
                 Key: HDFS-4951
                 URL: https://issues.apache.org/jira/browse/HDFS-4951
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: security
    Affects Versions: 3.0.0
            Reporter: Robert Kanter
            Assignee: Robert Kanter


It looks like there isn't a {{TokenRenewer}} for HttpFS delegation tokens ({{HTTPFS_DELEGATION_TOKENS}}
tokens, so when it goes to cancel the token, it throws an exception:

$ hadoop fs -ls webhdfs://host:14000

WebHDFS doesn't have this problem because it has a {{TokenRenewer}}.
