Robert Metzger commented on FLINK-5989:

> Project: Flink
> Issue Type: Improvement
> Components: Build System
> Reporter: Wenlong Lyu

> Currently akka introduces dependency on protobuf, which is a common jar used
> in many systems, I think we need to use a shaded akka like what we do in
> dependency on hadoop to avoid version conflicts with user code.
