@jongyoul unfortunately, I still have this issue. And the only place you
use custom classloader is in `ClusterManagerFactory.java`. But I only see you
use it to load the ClusterManager class (like
org.apache.zeppelin.cluster.yarn.Client), I don't find you use it to load other
hadoop classes. Let me know if I miss anything.
