> Enable cube planner phase one
> -----------------------------
>
> Key: KYLIN-2802
> URL: https://issues.apache.org/jira/browse/KYLIN-2802
> Project: Kylin
> Issue Type: Sub-task
> Affects Versions: v2.1.0
> Reporter: Zhong Yanghong
> Assignee: Wang Ken
> Priority: Major
> Fix For: v2.2.0
>
>
> This phase happens during cube building. To be able to trigger cube planner,
> one of the following preconditions should be satisfied.
> * The cube is empty
> * Job is for refreshing the only one segment.
> Since cube planner is based on cuboid row count, if the first segment is
> empty and there's no useful row count info, cube planner should not be
> triggered in this phase.
> We also introduce a threshold. If the total number of defined cuboids is less
> than this threshold, cube planner should not be triggered.
