-----------------------------------
Summary: the method closeSession of SessionManager has a
synchronized, is it able to be removed?
Key: HIVE-19624
URL: https://issues.apache.org/jira/browse/HIVE-19624
Project: Hive
Issue Type: Wish
Components: HiveServer2
Affects Versions: 2.1.1
Reporter: xulongfetion
The methods closeSession of
org.apache.hive.service.cli.session.SessionManager use
synchronized for thread safe, i looked at the code and wonder why there's need
for synchronized.
Because closeSession sometimes use the hadoop ipc call and takes too much time
to response, so if it is possible to remove the keyword synchronized.
