Hi geeks,
I want to debug into Kylin's web server to find out how some internals work.
I've followed steps in
http://kylin.incubator.apache.org/docs/development/dev_env.html
<http://kylin.incubator.apache.org/docs/development/dev_env.html> to set up my
dev environment and have successfully run the BuildCubeWithEngineTest. However
the section "Launch Kylin Web Server" seems a little outdated.
I tried to run org.apache.kylin.rest.DebugTomcat in IDEA and got the following
error:
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError:

Could you help provide some information about how to debug the server? I'm
using the latest code in 0.7 branch.
Best Regards,
Dayue
