------------------------------------------
Summary: Run selected qtest on different metastore backends
Key: HIVE-26005
URL: https://issues.apache.org/jira/browse/HIVE-26005
Project: Hive
Issue Type: Improvement
Components: Testing Infrastructure
Reporter: Stamatis Zampetakis
In various cases there are bugs which affect only certain types of metastore
databases (e.g., HIVE-26000) and it would be nice to be able to specify for
each test or a bunch of tests which metastore backend to use and have these
tests consistently running in CI.
After HIVE-21954, it is possible to run qtests on different metastores by
setting the system property {{test.metastore.db}} or introducing new
[AbstractCliConfig|https://github.com/apache/hive/blob/fcd0a47c2e27defb04247ffca6da11734e3e25c3/itests/util/src/main/java/org/apache/hadoop/hive/cli/control/AbstractCliConfig.java]
configuration with a new driver etc.
The naive way of implementing this task would be to copy an existing
configuration, change the metastore type, select the input files, and create a
new driver (probably again a copy from {{CoreCliDriver}}.
Other ideas would be to allow a driver to run with multiple configurations, or
handle the selection of the metastore type via QT options (similar to what was
done in HIVE-25594).
