Hi,
I think this is related to this unresolved JIRA. KYLIN-1605
<https://issues.apache.org/jira/browse/KYLIN-1605>
I mean the posibility of migrate metadata from source, data model, cube
definition or all project in order to re build the all cube, e.g. with
different Hadoop cluster.
Thanks!

Hi Shaofeng,
Do you think the CubeMetaExtractor and CubeMetaIngestor could do the
this job?

I see; currently, there is no support for this. But it should
be easy. Just look at `bin/metastore.sh`, you can extend the
function there: e.g, add the project as an optional parameter
(when specified, only export that project's metadata). After
the cube be imported in new environment, you can call the API
to purge it (clear segments), and then rebuild it from source.

Hi ShaoFeng Shi,
Sorry, I forgot to give more details. I would kike to
export a Project metadata including the following:
* Data sources (Hive Tables)
* Data Model definition
* Cube definition
That is to say, I need the metadata necesary to build the
same cube from a similar data source in a new cluster and
HBase storage. However I do not need data about HBase
table. E.g. I add a new dimension on Pre Production cube
and I would like to update this cube definition on
Production environment.
Best Regards,

Hi Roberto,
What kind of metadata are you going to export from
pre-production to production? Is it a single cube or
whole metadata set? Need more about your scenario to
understand the requirement.

Hi,
I have to two Kylin servers, one for Pre-Production
and another one for Production. What is the best way
to export project metadata between the two? I could
think if use metatada backup tools the metadata will
be related to Hbase tables in Pre-Production.
Is metadata backup the best way or what do you
recomend to copy metadata between pre and production
servers?
Thanks in advance,
Roberto
