> Currently when the AtlasPluginClassLoader is deactivated it sets the current threads class loader to class loader that was active when the class was instantiated. In applications like Hive where a single thread may be shared among multiple sessions each with its own class loader this is breaking class loading for UDFs. The deactivate method should set the current threads class loader back to the class loader that was set when activate was called.
