Colin Patrick McCabe commented on HTRACE-247:
---------------------------------------------
Keep in mind the webapp is just a front-end on top of some daemon or service
storing spans. In the past, this daemon has been htraced. We would like to
eventually teach the webapp to talk to hbase, but this work hasn't been done
yet. So I think what you're seeing is normal and expected if you are not
running htraced. HTRACE-226 has been filed for the work of integrating
htrace-webapp with htrace-hbase, but it's not yet done.
> Add instructions to htrace-webapp/README.md demonstrating how to use the web

> Right now I literally have no idea how to use the Web Application. This issue
> became apparent to me whilst trying to build the docker container and running
> into some Tomcat issues, then investigating the Web App locally only to find
> out that I couldn't package it. I then logged HTRACE-246.
> When I deployed the web app into Apache Tomcat and navigated to
> http://localhost:8080/htrace-webapp-4.1.0-incubating-SNAPSHOT/#about I am
> greeted with some concerning message the there is an error with regards to a
> REST service not being found!
> Please see the attached screenshot which shows you what I am seeing.
> I have tried starting up the REST server as per
> {code}

> However this does not resolve the issue and I still cannot bind to any RESt
> service at the /server/info endpoint.
> Can anyone help me to understand this?
> The issue describes the fact that we need to augment the documentation for
> the Web Application. Whether or not that happens in the webapp README I don't
> care. But the documentation should be easy to find.
> Thanks folks.
