Github user aarondav commented on the pull request: https://github.com/apache/incubator-spark/pull/586#issuecomment-35820063 Do you think it would be possible to separate this into two patches, one for the code warnings and one for the build issues? Code warnings are relatively easy to clean up without issue (and thus merge quickly), but we need to be very careful with dependencies; i.e., we need to go in and confirm that every change is not adding or removing actual dependencies. The dependencies changes can also be incorporated into a more general "clean up the build file" type patch, since I noticed that there may be other issues, like spark streaming including commons-io when it is already included in sharedSettings.
