Work Description: steveloughran commented on pull request #2816:
URL: https://github.com/apache/hadoop/pull/2816#issuecomment-806068773
This is a great start!
now, is there any way we can get the hadoop-api wrappers to bind to open
telemetry without needing all the new jars on the CP? As I think while it's
fine to have them on the path during compilation, at runtime it's adding a lot
more dependencies.
In fact, I worry about what transitive dependencies they pull it which will
have people downstream of hadoop common "expressing their concerns" -or worse,
refusing to upgrade.

> 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.
