I'm facing classpath issues particularly with Guava. Any suggestions on how to go about it? I was think maybe we can have an integration testing module per framework. For example for MR we'd have `mr-runtime` module which would be shaded. Now to test MR we could have a `mr-runtime-test` module which can setup DFS and MR clusters. Since mr runtime would be shaded completely we can write these integration tests. I've added more unit test though. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
