kangkaisen created KYLIN-2993:
---------------------------------

             Summary: Add special mr config for base cuboid step
                 Key: KYLIN-2993
                 URL: https://issues.apache.org/jira/browse/KYLIN-2993
             Project: Kylin
          Issue Type: Improvement
          Components: Job Engine
    Affects Versions: v2.1.0
            Reporter: kangkaisen
            Assignee: kangkaisen
            Priority: Major


Refer to http://kylin.apache.org/blog/2016/08/01/count-distinct-in-kylin/, currently, if user want to enlarge MR memory for global dict, they must use kylin.engine.mr.config-override., which will enlarge the memory of  all mr job. In fact, we only need to enlarge the memory for "Build Base Cuboid", so we could add a special mr config for base cuboid step.
