For the curious people, here is something which confirms that NARs have their own isolated Classloader. https://docs.hortonworks.com/HDPDocuments/HDF2/HDF-2.1.2/bk_dataflow-developer-guide/content/nars.html
EventAccess is an interface which has been loaded parent classloader(I guess) and hence it is accessible in NAR classloader. However, it brings me to next question. Is there any documentation to indicate what has been/would be loaded in which classloader? Thanks Santosh
