Hi,
Does anybody have some idea why we get this:

It builds/runs for me locally, if we didn't have these resources, it would not
build for me either.

> HTrace is not perfectly integrated into HBase, the version 3.2.0 is buggy,
> the upgrade to 4.x is not trivial and would take time. It might not worth to
> keep it in this state, so would be better to remove it.
> Of course it doesn't mean tracing would be useless, just that in this form
> the use of HTrace 3.2 might not add any value to the project and fixing it
> would be far too much effort.
> ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
> Based on the decision of the community we keep htrace now and update version
