    Description

      Currently, we can not change build engine without disable cube and purging all existing segments. But it is expensive。

      After my test building cube with MR engine and Spark engine, there generate the same result, and Merge job always use mr engine. Hence, I think take engineType as a part of cube's Signature is improper。

      I change the code and modify cube json. it work will with MR and spark engine Alternately。

      TO BE DONE：modify web UI.
