    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);
                  }
