[jira] [Commented] (KYLIN-1706) Allow cube to override MR job configuration by properties

    [ https://issues.apache.org/jira/browse/KYLIN-1706?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15288602#comment-15288602 ] 

liyang commented on KYLIN-1706:
-------------------------------

The design is to allow override MR config by kylin properties with a prefix. E.g., below kylin properties override "mapreduce.job.queuename" to all MR jobs. User can also apply this property at cube level.

kylin.job.mr.config.override.mapreduce.job.queuename=YOUR_QUEUE

> Allow cube to override MR job configuration by properties

> Currently cube can specify MR job configuration by a job_conf.xml file under conf/. This is still not sufficient for example, to specify 50+ different job queues, user will have to maintain 50+ different job_conf.xml files.
> By allowing config override from kylin properties, the 50+ job queue case will become a lot more easier.
