Wei-Chiu Chuang commented on HBASE-23755:
-----------------------------------------
Thanks. Didn't realize the docs are patched against master.
Don't think there's any public API change. Probably the only user facing stuff
is the configuration hbase.trace.spanreceiver.classes and the hbase shell
(there's a trace command)
I'm thinking to update the doc to deprecate Htrace in the master branch now.
The doc for opentracing will be in the feature branch, which will get added to
doc when the branch is merged into trunk.

> The trace doesn't work at all in HBase 2.0 and above after HBASE-18601 (the
> trace doesn't get picked up at the server side). We should make a note in the
> user doc stating it is
> # unusable
> # deprecated in HBase 2.x because HTrace is in Attic.
> # removed from HBase 3.0 and above.
