[jira] [Created] (HDFS-4568) NN should require authenticated connections to cancel tokens

Daryn Sharp created HDFS-4568:
---------------------------------

             Summary: NN should require authenticated connections to cancel tokens
                 Key: HDFS-4568
                 URL: https://issues.apache.org/jira/browse/HDFS-4568
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode, security
    Affects Versions: 2.0.0-alpha, 0.23.0, 3.0.0
            Reporter: Daryn Sharp


The NN requires get/renew token operations to be securely authenticated - ie. you can't use a token to get/renew a token.  However, token cancelation is allowed with a token, including using a token to cancel itself.  Cancelation should perform the same authentication checks as get/renew.
