Hi All, As far as I know the actual integration of HTrace 3.2 into HBase is far from satisfying.
This version of the library is old, buggy, not really maintained and the migration to version 4.x is quite hard ( https://issues.apache.org/jira/browse/HBASE-14451) and looks like the task is not getting much closer to the goal. This is why I think we should remove HTrace now and if we still want to have some art of tracing (I think it would be useful) then start it from the baseline. I have created a ticket for this task: https://issues.apache.org/jira/browse/HBASE-18601 The removal could be quite fast and reach version 2.0.0 too. What do you all think? Thanks, Tamaas
