Ben Sigelman commented on HADOOP-15566:
---------------------------------------
Hi all – someone sent this my way. I am one of the opentracing co-creators and
would be delighted to collaborate on adding (minimal-dependency, lightweight)
OpenTracing instrumentation to ASF projects. In serendipitous news, we have
recently added some resources to help with the actual instrumentation work for
well-used and well-loved projects like those in the ASF.
(PS: I am generally oversubscribed and can be bad at things like JIRA, but am
100% happy to help here... if I'm being flaky about Jira responses, please
reach out to me at [b...@gmail.com|mailto:b...@gmail.com] where I maintain a
better SLA ;))
> 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.
