There is no fundamental difference between these two. After we call
`conf.addResouorce("hive-site.xml")`, `Configuration` internally will use
classloader's `getResource` to find the url of the resource. At here,
`Utils.getContextOrSparkClassLoader.getResource("hive-site.xml")` just
explicitly get the url.
