>
> With `spark-submit`, jars specified via `--jars` are added to distributed cache in `yarn-cluster` mode. The executor should add cached jars to classpath. However, 
> {code}
> sc.parallelize(0 to 10, 10).map { i =>
>   System.getProperty("java.class.path")
> }.collect().foreach(println)
> {code}
> shows only system jars, `app.jar`, and `spark.jar` but not other jars in the distributed cache.
> The workaround is using assembly jar.
