      Description

      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
      // File listing omitted
      13/06/21 13:09:04 WARN token.Token: No TokenRenewer defined for token kind HTTPFS_DELEGATION_TOKEN
      13/06/21 13:09:04 WARN util.ShutdownHookManager: ShutdownHook 'ClientFinalizer' failed, java.lang.UnsupportedOperationException: Token cancel is not supported  for HTTPFS_DELEGATION_TOKEN tokens

      	at org.apache.hadoop.util.ShutdownHookManager$1.run(ShutdownHookManager.java:54)
      

      WebHDFS doesn't have this problem because it has a TokenRenewer for its delegation tokens ("WEBHDFS delegation" tokens).
