      Description

      When old token is expiring and being removed, it's not removed from the allTokens map, resulting in possible leak. 

      if (t.token.getKind().equals(new Text("HDFS_DELEGATION_TOKEN"))) {
              iter.remove();
              t.cancelTimer();
              LOG.info("Removed expiring token " + t);
            }
