Description

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).
