      Description

      Currently when migrating a kylin cluster from on data center to the other or the hbase cluster the kylin depends on will be changed from one cluster to the other, there will be a long down time to migrating the history data from one cluster to the other or we must rebuild all the history data of cube in the other cluster.

      In xiaomi, we added the support of secondary hbase storage and made the kylin cluster can query cube data from the old hbase cluster during the migration.

      As a result,  the  migration is very smooth with minimum down time.
