Aaron Fabbri commented on HADOOP-15566:
---------------------------------------
Agreed. Htrace is great but suffered from everyone being too busy to give it
the love it needed to develop.
We're going to spend some time seeing if we can plug in an opentracing
implementation today. Will report back with any interesting findings.
> Remove HTrace support
> ---------------------
>
> Key: HADOOP-15566
> URL: https://issues.apache.org/jira/browse/HADOOP-15566
> Project: Hadoop Common
> Issue Type: Improvement
> Components: metrics
> Affects Versions: 3.1.0
> Reporter: Todd Lipcon
> Priority: Major
>
> The HTrace incubator project has voted to retire itself and won't be making
> further releases. The Hadoop project currently has various hooks with HTrace.
> It seems in some cases (eg HDFS-13702) these hooks have had measurable
> performance overhead. Given these two factors, I think we should consider
> removing the HTrace integration. If there is someone willing to do the work,
> replacing it with OpenTracing might be a better choice since there is an
> active community.
