-----------------------------------
Summary: HiveServer/HiveServer2 leaks jdbc connections when
network interrupt
Key: HIVE-7081
URL: https://issues.apache.org/jira/browse/HIVE-7081
Project: Hive
Issue Type: Bug
Components: HiveServer2, JDBC
Affects Versions: 0.13.0, 0.12.0
Environment: hadoop 1.2.1
hive 0.12.0 / hive 0.13.0
linux 2.6.32
Reporter: Wang Zhiqiang
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()。
