> The driver has been introduced back in 2015 (HIVE-6010) aiming to run queries with vectorization on/off and comparing the results. However it didn't receive much attention since then and currently only two queries are run with this driver.
> The majority of tests aiming to ensure vectorization works correctly use the {{TestMiniLlapLocalCliDriver}} and run a query twice switching on/off the necessary properties.
> Summing up having the [TestCompareCliDriver|https://github.com/apache/hive/blob/d521f149fade25f74e7ca28fa399103684a80580/itests/qtest/src/test/java/org/apache/hadoop/hive/cli/TestCompareCliDriver.java] in the repo leads to extra code maintenance cost without significant benefit.
