同一个 cube不同segment无法并行构建
当我对同一个cube并行构建不同segment的时候，提示我无法并行构建，这是为什么呢，不同segment同时构建会有什么影响吗？

There isn't any ready segment for the cube. After build a segment successfully, you can parallel build other segments

Hi,
This looks has relation with cube planner feature. The purpose is to avoid build job and optimize job run concurrently, because they can both modify the cuboid set and caused some bugs. This only happen when cube planner is enabled and there has no READY segment.
You can check the source code at https://github.com/apache/kylin/blob/c507ae29fa64bc7234efd6a002dcfe990969ad35/server-base/src/main/java/org/apache/kylin/rest/service/JobService.java#L417 , or refer to https://github.com/apache/kylin/pull/85/commits/42f8e073d7f381af7e50660099cfdd6200066363 and https://issues.apache.org/jira/browse/KYLIN-2733.
