> Improve fidelity of RegionLocator spans
> ---------------------------------------

> Key: HBASE-26648
> URL: https://issues.apache.org/jira/browse/HBASE-26648
> Project: HBase
> Issue Type: Sub-task
> Components: tracing
> Reporter: Nick Dimiduk
> Assignee: Nick Dimiduk
> Priority: Major
> Fix For: 2.5.0, 3.0.0-alpha-3
>
>
> While backporting HBASE-26474 to branch-2, I realized that the nuance of
> tracing of region locator calls is lacking. In the current implementation,
> all calls to the region locator produce {{SpanKind.CLIENT}} spans. This is
> correct only for the code path where the client reaches out to a remote host
> to populate cache locations. This doesn't happen every time.
> Instead, the top-level span should be {{SpanKind.INTERNAL}} and only when a
> region location must be requested remotely should we create a child span with
> {{SpanKind.CLIENT}}.
