Zhou Sheng commented on HDFS-2028:
----------------------------------
I checkout version 0.20.205 from svn
(http://svn.apache.org/repos/asf/hadoop/common/branches/branch-0.20-security-205/)
and built the new core jar.
After replacing the core jar, the problem still retains. When I load data into
tables of hive via hiver cli or hive server, there are always some ESTABLISHED
status socket connections.
> There are lot of ESTABLISHED socket connetions at 50010 port.
