------------------------------------
Summary: Dependencies not on classpath lead to runtime startup
error
Key: TWILL-215
URL: https://issues.apache.org/jira/browse/TWILL-215
Project: Apache Twill
Issue Type: Bug
Components: core
Affects Versions: 0.9.0
Reporter: Martin Serrano
Priority: Critical
Fix For: 0.10.0
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.
