I think you need to add the otel-agent jar as a dependency to hadoop-common
and exclude it as a dependency from hadoop-client. then it'll show up in
`share/hadoop/common/lib`. That's still not quite right though, because we
don't want the agent to be included in any runtime class path, only to be
available to inclusion via `-javaagent:...`.

> 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.
