add single point where System.exit() is called for better handling in containers
--------------------------------------------------------------------------------

                 Key: HADOOP-8096
                 URL: https://issues.apache.org/jira/browse/HADOOP-8096
             Project: Hadoop Common
          Issue Type: New Feature
          Components: util
    Affects Versions: 0.24.0
            Reporter: Steve Loughran
             Fix For: 0.24.0


with plans for OSGI integration afoot in HADOOP-7977, Hadoop needs unified place where System.exit() calls. When one runs any bit of Hadoop in a containers the container will block those exits with a security manager and convert the calls into security exceptions. A single exit method would enable such exceptions to be logged, and conceivably handled slightly more gracefully (e.g. tell the daemon to die).
