------------------------------------------
Summary: Drop support for multi-threaded qtest execution via
QTestRunnerUtils
Key: HIVE-25681
URL: https://issues.apache.org/jira/browse/HIVE-25681
Project: Hive
Issue Type: Task
Components: Testing Infrastructure
Affects Versions: 4.0.0
Reporter: Stamatis Zampetakis
Assignee: Stamatis Zampetakis
There is an option for running qtest concurrently via
[QTestRunnerUtils#queryListRunnerMultiThreaded|https://github.com/apache/hive/blob/a72db99676ca6a79b414906ab78963a3e955ae69/itests/util/src/main/java/org/apache/hadoop/hive/ql/QTestRunnerUtils.java#L128]
but it is not in use for more than a year now.
Moreover, with the move the kubernetes containerized test execution
(HIVE-22942) it is unlikely that we will run concurrent tests using these APIs
anytime soon.
The only consumer of this API at the moment is
[TestMTQueries|https://github.com/apache/hive/blob/master/itests/hive-unit/src/test/java/org/apache/hadoop/hive/ql/TestMTQueries.java]
which is disabled and it basically corresponds to the unit tests for these
APIs.
I propose to drop these APIs and related test to facilitate code evolution and
maintenance.
