he yongqiang resolved HADOOP-3701.
----------------------------------

       Resolution: Fixed
    Fix Version/s: 0.17.0

this error seems is caused by jdk 1.5's bug :http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6215050
i replace all the occurrence of SocketSelector.open().socket() with new Socket(). It seems
work.

> 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)
