Greetings, As you have probably heard of, HTrace is no more. We as a community need to find a solution to replace HTrace. There's currently a great discussion on a good replacement (HADOOP-15566 <https://issues.apache.org/jira/browse/HADOOP-15566>) and I urge you to participate in the discussion if you aren't aware of this discussion yet.
For a bit of history/contenxt: HTrace is a distributed tracing system specifically designed for Hadoop ecosystem projects, and its tracing coding is embedded in Hadoop and HBase. Over the years, its activity diminished while other distributed tracing technologies are getting more adoption. As a Hadoop developer/supporter, the lack of ability to diagnose performance issues in a large cluster has been always been a major supportability gap for us, and it's getting worse as users onboard more variety of workloads. I believe you feel the pain as well. Let's settle on a plan and add this critically important feature in a better state. Best -- A very happy Hadoop contributor
