@ArkenKiran where do you get the opentelemetry-agent jar for your testing?
I've built this patch and it appears that the agent jar is not included.
```
$ mvn clean install -Pdist -DskipTests -Dtar -Dmaven.javadoc.skip=true
...
$ cd /tmp
$ tar xzf
~/repos/apache/hadoop/hadoop-dist/target/hadoop-3.4.0-SNAPSHOT.tar.gz
$ cd hadoop-3.4.0-SNAPSHOT
$ ls -1 share/hadoop/common/lib/ | grep opentel
opentelemetry-api-1.3.0.jar
opentelemetry-context-1.3.0.jar
```

> The HTrace incubator project has voted to retire itself and won't be making
> further releases. The Hadoop project currently has various hooks with HTrace.
> It seems in some cases (eg HDFS-13702) these hooks have had measurable
> performance overhead. Given these two factors, I think we should consider
> removing the HTrace integration. If there is someone willing to do the work,
> replacing it with OpenTracing might be a better choice since there is an
> active community.
