Examples of org.apache.hadoop.yarn.YarnUncaughtExceptionHandler

org.apache.hadoop.yarn.YarnUncaughtExceptionHandler
This class is intended to be installed by calling {@link Thread#setDefaultUncaughtExceptionHandler(UncaughtExceptionHandler)}In the main entry point. It is intended to try and cleanly shut down programs using the Yarn Event framework. Note: Right now it only will shut down the program if a Error is caught, but not any other exception. Anything else is just logged.
