Description

Atlas hooks and server currently register a shutdown hook directly with java Runtime object. Hadoop provides an utility class, ShutdownHookManager, which helps to ensure that the hooks are called in a well defined order. Atlas hook registration should be updated to register its shutdown hook with Hadoop's ShutdownHookManager:
