    Description

      We encounted too many open files exception.
      And we found the datanode server daemon has opened too many sockets and pipes. And more surprisingly,most of the sockets are connects to remote data node's 50010 port and are with state CLOSE_WAIT,such as
      tcp 1 0 ::ffff:10.61.0.161:33776 ::ffff:10.61.0.162:50010 CLOSE_WAIT 27637/java off (0.00/0/0)
