> Start job scheduler need to acquire job lock from zookeeper, when lock acquire fail, it will throw an IllegalException, but because the scheduler is started in a new thread, the exception thrown by the thread will be ignored, and the server still started successfully, and no exceptions are logged. That make it hard for trouble shooting, should change to make server started fail when the scheduler started fail.
