> For now, MR job conf could be overwritten by kylin_job_conf.xml file, and also further overwritten at project/cube level.
> Nonetheless, when resuming a MR job after a job server restarting or other kind of interruption, we only use the default conf to trace the job status.
> That's usually not a problem until user hope to overwrite job status tracing related parameters (job history server address e.g.) to support multi history servers.
