what issue is this?

[王斌]

when run zipkin collector service,  we encounter this problem as below? Why this happened? We find this class in zipkin-scrooge-1.2.0-SNAPSHOT.jar, but can't load it. Don't understand why.

Any help? Thanks so muth!

Suspect it was a classpath problem. Unless you are patching zipkin, best to use the uber jars directly or something like docker. https://github.com/openzipkin/docker-zipkin
