>
> 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.
