Stamatis Zampetakis created HIVE-28340:
------------------------------------------
Summary: Test concurrent JDBC connections with Kerberized cluster,
impersonation, and HTTP transport
Key: HIVE-28340
URL: https://issues.apache.org/jira/browse/HIVE-28340
Project: Hive
Issue Type: Test
Components: HiveServer2
Reporter: Stamatis Zampetakis
Assignee: Stamatis Zampetakis
The new test case simulates a scenario with two JDBC clients doing the
following in parallel:
* client 1, continuously opens and closes connections (short-lived connection)
* client 2, opens connection, sends fixed number of simple queries, closes
connection (long-lived connection)
Since the clients are running in parallel we have one long-lived session in HS2
interleaved with many short ones.
The test case aims to increase test coverage and guard against regressions in
the presence of many interleaved HS2 sessions.
In older versions, without HIVE-27201, this test fails (with the exception
outlined below) when the cluster is Kerberized, and we are using HTTP transport
mode with impersonation enabled.
