> Two cubes use the same lookup table, and then the lookup table data in Hive changes. One of Kylin's cubes builds the new data, and the other doesn't. When Kylin queries the lookup table, there is no mechanism to choose which cube being used. So it maybe gets the error result. I have an idea, choose the latest cube to answer the query.
