[jira] [Created] (HADOOP-9064) Augment DelegationTokenRenewer API to cancel the tokens on calls to removeRenewAction

Karthik Kambatla created HADOOP-9064:
----------------------------------------

             Summary: Augment DelegationTokenRenewer API to cancel the tokens on calls to removeRenewAction
                 Key: HADOOP-9064
                 URL: https://issues.apache.org/jira/browse/HADOOP-9064
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
    Affects Versions: 2.0.2-alpha
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla


Post HADOOP-9049, FileSystems register with DelegationTokenRenewer (a singleton), to renew tokens. 

To avoid a bunch of defunct tokens clog the NN, we should augment the API to {{#removeRenewAction(boolean cancel)}} and cancel the token appropriately.
