> Currently, users can override MR config at project/cube level via kylin
> properties {{kylin.engine.mr.config-override.}}
> However, this applies to all MR steps. It is more reasonable to add
> override-configs only for certain memory-hungry steps like in-mem cubing and
> "Build columnar page index"
