    [ https://issues.apache.org/jira/browse/HDFS-2028?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13048500#comment-13048500

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.

> When I load data into tables of hive via hiver cli or hive server, there are always some
ESTABLISHED or CLOSE_WAIT status socket connections. And these tcp connections won't be released
unless you quit hive or restart hiveserver.
