Hi
Note that the different Kylin environments should share the same Hadoop
cluster, including HDFS, HBase and HIVE.
The doc says that should share the same Hadoop cluster, including HDFS, HBase
and HIVE, right?
Thanks & Regards
Lionel

Hi,
As the doc says, it could migrate cube between different clusters.
If you have a kylin instance in QA cluster (qa_node:7070), and you want to
migrate to a PROD cluster (prod_node:7070), you can use qa_node:7070 as
srcKylinConfigUri and prod_node:7070 as dstKylinConfigUri, thus to migrate
across cluster.

Hi Xiaoxiang,
CubeMigrationCLI.java can migrate a cube from a Kylin environment to
another, for example, promote a well tested cube from the testing env to
production env. Note that the different Kylin environments should share the
same Hadoop cluster, including HDFS, HBase and HIVE.
Per the document, cannot migrate across cluster?
We are finding a solution to do this and QA & PROD are in different cluster.
Can you help give more advice?
Thanks & Regards
Lionel

Hi Lionel,
It is a good practice to do a full test at test env and migrate it to
another env, I think you can use CubeMigrationCLI to meet your request.

Hi Kylin dev,
We are now trying Kylin for our OLAP system, and now have some
questions need clarify with you :
1. See that cannot use CLI to migrate data from QA environment to
PROD if they are in different cluster, what's the limitation when migrate
across clusters and then how can do the migration?
2. We have tried with metastore.sh backup and then restore in
another cluster, Will this be a solution for migration? And any impact if using
this solution?
Thanks & Regards
Lionel
