Subject Re: [VOTE] HTrace 4.0 Release Candidate 0
Date Wed, 09 Sep 2015 01:32:27 GMT
Thanks for putting this up, Colin.

- verified mds and signature
- ran "mvn install" without test failure
- ran "mvn package -Pnative" without test failure in htrace-c
- built src tarball by running "mvn clean install -DskipTests 
assembly:single -Pdist"
- launched htraced and sent test tracing spans by HTracedRESTReceiver 
and checked the spans by Web-UI

I'm +1 if the issue about NOTICE.txt Lewis pointed out is not critical 
for release.
