> is a follow-up survey for HIVE-28295 and HIVE-28315 .
> - I created the smallest unit test at
> [https://github.com/linghengqian/hive-embedded-mode-test]. The following
> command verification is executed under the Ubuntu 22.04.4 of the installation.
> {code:bash}
> sdk install java 8.0.422-tem
> sdk use java 8.0.422-tem
> sdk install maven
> git clone g...@github.com:apache/hive.git
> cd ./hive/
> git reset --hard 929305f077f5e40311939ce7256adb3b35d985b0
> mvn clean install -DskipTests -T1C
> cd ../
> git clone g...@github.com:linghengqian/hive-embedded-mode-test.git
> cd ./hive-embedded-mode-test/
> mkdir -p /tmp/hive
> chmod -R 777 /tmp/hive
> ./mvnw clean test
