YARN-11939. UT TestAuxServices breaking on Clover

[ferdelyi]

Disable OpenClover for **/TestAuxServices.java in the hadoop-yarn-server-nodemanager, as OpenClover implementation in the UT TestAuxServices breaks on Java 17

Hadoop currently uses clover-maven-plugin.version 4.4.1. (no Java 17 support).

Description of PR

In OpenClover 4.5. Java 17 is experimental as of the latest release:https://openclover.org/doc/openclover-4.5.2-release-notes.html

There was an earlier suggestion to use Jacoco instead of Unit Test.

HADOOP-15190 “Use Jacoco to generate Unit Test coverage reports”

How was this patch tested?

Manually tested on my local machine if UT runs OK with Java 17 after the exlusion:

java -version
export JAVA_HOME=$(/usr/libexec/java_home -v 17)
cd hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager
mvn clean clover:setup test -Dtest=TestAuxServices

does upgrading work?

[pan3793]

Manually tested on my local machine if UT runs OK with Java 17 after the exlusion.

it's better to provide a copy-pastable command, so that reviewers are easy to verify that.

@pan3793 thank you for your feedback, you are right. Updated the PR description with the below:

java -version
export JAVA_HOME=$(/usr/libexec/java_home -v 17)
cd hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager
mvn clean clover:setup test -Dtest=TestAuxServices

@pan3793 thank you for your question, I've tried bumping up the OpenClover version number to 4.5.2., but I'm hitting the same issue.
Adding the --add-opens flags won't help either, because we are hitting here a ClassLoader isolation issue.
