Connecting to a Yandex Object Storage bucket with a bucket policy

In Hive Metastore, you can work with an Yandex Object Storage bucket with bucket policies configured. You access the bucket from a separate DNS zone through an internal load balancer used to distribute traffic among NAT instances. The described connection is shown below. A Metastore cluster will be used in place of the test-s3-vm VM.

Getting startedGetting started

1. Create a network infrastructure to access the Object Storage bucket as shown on the picture above. For information on how to create such an infrastructure, see this tutorial.
2. Test the new infrastructure.

Prepare the Metastore clusterPrepare the Metastore cluster

1. Create a service account named my-account with the storage.uploader and managed-metastore.integrationProvider roles.
2. Grant the READ and WRITE permission to the my-account service account for the bucket you created earlier.
3. Configure the network and create a Metastore cluster. When creating it, specify the my-account service account.

Test the connectionTest the connection

To test the Object Storage bucket connection, export the Metastore cluster data to that bucket.
