For some cube building jobs, kylin chooses im-memory cubing. However, this choice is not good for some users due to large memory cost. Customers may be able to tolerate with long cube building time, but is not able to tolerate with large memory cost, which may lead to cube building MR job failure. Therefore, it may be better to provide a parameter for setting whether automatically decide the strategy or manually.
