Yandex Data Processing cluster is in the UNKNOWN state right after it has been created

Issue descriptionIssue description

After you create a Yandex Data Processing cluster, its nodes remain in the UNKNOWN state.

SolutionSolution

A cluster may be in the UNKNOWN state if you are creating its VMs without public IP addresses. They are not available from the internet and do not have internet access by default.

To grant online access to these instances, you will need to use a NAT gateway.

1. Create a NAT gateway.
2. Add a route table, selecting the gateway you created as a next-hop node.
3. Link the routing table to the subnet with the cluster's VMs.
4. Set up security groups if required. If you do not use security groups, skip this step.

As a result, the cluster should change to RUNNING within a few minutes.
