> Key: KYLIN-4175
> URL: https://issues.apache.org/jira/browse/KYLIN-4175
> Project: Kylin
> Issue Type: Improvement
> Reporter: Liu Shaohui
> Assignee: Liu Shaohui
> Priority: Major
>
> 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.
