Description
According to the following bit of comments:
public interface Dispatcher { // Configuration to make sure dispatcher crashes but doesn't do system-exit in // case of errors. By default, it should be false, so that tests are not // affected. For all daemons it should be explicitly set to true so that // daemons can crash instead of hanging around. public static final String DISPATCHER_EXIT_ON_ERROR_KEY = "yarn.dispatcher.exit-on-error";
we should really make sure to set it to true in our configs.
