Hugo and I were discussing a case were the shading should happen at the last step, rather than what we do today.
I think there are 3 possible strategies of shading that one can do: (1) pre-shade some of your dependencies, so that your other dependencies can work. This what we do today, we shade PB+ GRPC, etc so that Hadoop can work. (2) pre-shade some of your dependencies' transitive dependencies so that you depend on already-shaded artifacts. This will be like having maven artifacts of shaded-hadoop so that hadoop itself does not bring in any more dependency. If hadoop has shaded artifacts, or we do shading of hadoop's dependencies in another repository, we won't need to pre-shade PB, etc. (3) post-shade. This means that in the code itself we do not depend on shaded packages anymore, but do the shading as a different module so that we publish shaded artifacts. This allows the downstreamers to be able to consume ratis, while allowing ratis source code to be saner. Obviously for doing (3), we need to kick out ratis-hadoop module to the hadoop project. Thinking about it, I think ratis-hadoop does not belong in Ratis itself anyway. What do you guys think about moving the code over to Hadoop, and getting rid of the hadoop dependency to end this shading madness? Enis
