HTrace 4.1 release candidate 1
Hi all,
I've posted the first release candidate for HTrace 4.1 here:
http://people.apache.org/~cmccabe/htrace/releases/4.1.0/rc1/
The jars have been staged here:
https://repository.apache.org/content/repositories/orgapachehtrace-1021
HTrace 4.1 brings a lot of robustness improvements. There were major
improvements to htraced and the web UI, as well as new metrics added.
There were numerous build fixups, and we added Docker support, to
ensure a repeatable build.
Check it out. The vote will run for 5 days.
cheers,
Colin

Thanks for putting this up, Colin.

This seemed not to be cherry-picked to branch-4.1.
I do not think this is critical but would like it to be in.
Except for this, the RC is good.
I built Hadoop against 4.1.0-incubating,
run HDFS operations with tracing enabled,
saw tracing by Web-UI of htraced.
It worked fine.

Thanks, guys. I will spin another RC with HTRACE-334 added. Can I
get a review of https://issues.apache.org/jira/browse/HTRACE-342 so
that I can add that as well? It's a very simple docs change.
