[jira] [Created] (KYLIN-2857) MR configuration should be overwritten by user specified parameters when resuming MR jobs

zhengdong created KYLIN-2857:
--------------------------------

             Summary: MR configuration should be overwritten by user specified parameters when resuming MR jobs
                 Key: KYLIN-2857
                 URL: https://issues.apache.org/jira/browse/KYLIN-2857
             Project: Kylin
          Issue Type: Improvement
          Components: Job Engine
            Reporter: zhengdong
            Assignee: Dong Li


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.
