> There are duplicate classes at runtime since 1.0+, because of multiple modules packaging. Two different JARs contain the same package but with different contents. Eg, both helix-core.jar and metrics-common.jar contains `SensorNameProvider.class`. And at tests runtime, we have a check to detect duplicate classes and this causes tests failure. > > The problem is, when we package the helix jars, the dependent subproject's classes are packaged into helix-core.jar: all classes in module helix-core and its dependencies match `org.apache.helix.*` are packaged to helix-core.jar. Then there are duplicate classes from metrics-common.jar/zookeeper-api.jar/helix-core.jar > > Though helix doesn't have duplicate classes in the same package, it is still not a good practice to package the same class into two different jars that have dependency relation. > I'm not understanding what kind of test failures we are seeing.
