Oozie launches a wrapper MapReduce job to run a Java job J1. Oozie's /lib/ directory is provided to the classpath of J1 as expected. This part works. The Java job J1 configures and launches a MapReduce job MR1. As part of the configuration, J1 tries to put some JARs on the distributed classpath for MR1 to use in its mappers and reducers. To do so, it calls DistributedCache.addFileToClassPath(jarfilePath). The file at jarfilePath DOES get added to the distributed cache. But the mapper for MR1 still throws a ClassNotFoundException, since the file at jarfilePath is NOT on the classpath for MR1. This is what doesn't work. I hope this explanation makes more sense. Thanks again for putting some thought to it.
