> REEF, Tang and Wake (and the several other subprojects) all have various utils packages that we should unify. For instance, there is a{{Pair}} class in reef-io and reef-common and there is a {{Tuple}} in reef-io that serves the same purpose.
> I propose to move all of these utilities into a common package {{org.apache.reef.utils}} with subpackages named after standard Java package names. For instance, the {{Pair}}, {{Tuple}} and {{MonotonicSet}} classes all would be in {{org.apache.reef.utils.collections}}.
> Also, those utilities should be in a new submodule called {{reef-utils}} which may not depend on anything but the JDK. That way, we don't run the risk of blowing up the dependency tree of current users.
