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).
