> We do not use logback in our environment but it is a dependency of {{ApplicationMasterMain}}.  When {{YarnTwillPreparer.createTwillJar}} is called in our environment, the logback jar is not on our classpath.   For a class not in the classpath, the {{Dependencies.findClassDependencies}} method ignores it.  This leads to a runtime startup error when the app master tries to start.
> This is easily fixed unless there some use case for ignoring the dependency when it is not on the classpath.  An exception should be thrown and no yarn job should be submitted.
