> Project: Kylin
> Issue Type: Bug
> Components: Job Engine
> Affects Versions: v1.5.1, v1.5.2
> Reporter: Ma Gang
> Assignee: Ma Gang
> Attachments: fix_swallow_scheduler_start_exception.patch
>
>
> 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.
