Creating a Hive Metastore cluster

To learn more about Metastore clusters in Yandex MetaData Hub, see Hive Metastore clusters.

Getting started:

1. Configure a network.
2. Configure security groups.
3. (Optional) Prepare a static access key.

Next, create a cluster.

Configure a networkConfigure a network

Set up a NAT gateway in the subnet the cluster will connect to. It is needed for the cluster to interact with Yandex Cloud services.

Configure security groupsConfigure security groups

If the cloud network uses security groups, they can hinder the cluster's operation. Set up the default security group to work with Metastore. To do this, add the following rules to it:

• For incoming client traffic:

  • Port range: 30000-32767
  • Protocol: Any (Any)
  • Source: CIDR
  • CIDR blocks: 0.0.0.0/0

• For incoming load balancer traffic:

  • Port range: 10256
  • Protocol: Any (Any)
  • Source: Load balancer healthchecks

If you plan to use multiple security groups for a cluster, enable all traffic between these groups.

(Optional) Prepare a static access key(Optional) Prepare a static access key

To enable a Metastore cluster to work with Yandex Object Storage, prepare a static access key:

1. Create a service account.

2. Assign the required roles to the service account.

   The roles you need depend on your use case scenario. You can view the service roles in the Metastore section and all the available roles in this reference.

3. Create a static access key for the service account.

4. Save the ID and secret key. You will not be able to access them later.
