Hi All,
Need advice, how we can export all the DDL of one scheme from Hive ( from QA region, a schema with around 2000 tables) to Dev or ACPT region, only DDL's needed to be in sync , not worried about the data, so do we have any option or script to import / export all the DDL's from one region to another region in one go, please suggest, thank you.

Hello @prakodi,
For CDH 6.3, you can review this article

You can use BDR to sync only dictionary

Hello @prakodi ,
You can use Hive Replication to migrate the schema from one cluster to another

Hi,
we need to sync only few schemas, this solution is completely moving all the metastore from one region to another region. Just for one schema which contains 100's of tables, we want to sync the DDL's to another region.

Hello @prakodi,
Thanks for your response!
You do have the option to select a single database in the general tab while creating hive replication policies. In the Replicate All parameter you can mention the single database.
Refer to this article:

Hi Tarun,
This solutions looks fine, but unfortunately we are still using CDH6.3 version only, so we dont use Ranger, so is there any option for CHD 6.3 version ?
Thanks,
