--------------------------------
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.
