[jira] [Commented] (HIVE-7081) HiveServer/HiveServer2 leaks jdbc
connections when network interrupt
[ https://issues.apache.org/jira/browse/HIVE-7081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14251358#comment-14251358 ]
Thejas M Nair commented on HIVE-7081:
-------------------------------------
I don't think HIVE-5799 will help to free up this thread. HIVE-6679 (or the upgrade to thrift 0.9.2) would be needed.

> HiveServer/HiveServer2 leaks jdbc connections when network between client and server is interrupted。
> I test both use DBVisualizer and write JDBC code，when the network between client and hiveserver/hiverserver2 is interrupted，the tcp connection in the server side will be in ESTABLISH state forever util the server is stoped。By Using jstack to print out server's thread, I found thread is doing socketRead0()。
