--------------------------------------------
Summary: HS2 sessionmanager should synchronize the call to
insert/remove session objects from session hash map
Key: HIVE-4628
URL: https://issues.apache.org/jira/browse/HIVE-4628
Project: Hive
Issue Type: Bug
Components: HiveServer2
Affects Versions: 0.11.0
Reporter: Shreepadma Venugopalan
Assignee: Shreepadma Venugopalan
Priority: Critical
HS2 SessionManager maintains a hashmap of active HS2 sessions. However, insert
and deletes to this hashmap is not synchronized. A consequence of this is a
racing thread could overwrite a valid session object in the hashmap and we
could end up losing a session!
