ListSegmentHosts

Retrieves a list of segment hosts for the specified cluster.

import { cloudApi, serviceClients, Session } from "@yandex-cloud/nodejs-sdk";

const ListClusterHostsRequest =
  cloudApi.dataproc.cluster_service.ListClusterHostsRequest;

(async () => {
  const authToken = process.env["YC_OAUTH_TOKEN"];
  const session = new Session({ oauthToken: authToken });
  const client = session.client(serviceClients.ClusterServiceClient);

  const result = await client.listSegmentHosts(
    ListClusterHostsRequest.fromPartial({
      // clusterId: "clusterId",
      // pageSize: 0,
      // pageToken: "pageToken",

ListClusterHostsRequest​

clusterId : string​

ID of the Greenplum® cluster.

To get the Greenplum® cluster ID use a ClusterService.List request.

pageSize : int64​

The maximum number of results per page to return.

If the number of available results is larger than page_size, the service returns a ListClusterHostsResponse.next_page_token that can be used to get the next page of results in subsequent list requests.

pageToken : string​

Page token. To get the next page of results, set page_token to the ListClusterHostsResponse.next_page_token returned by the previous list request.

ListClusterHostsResponse​

hosts : Host​

Requested list of hosts for the cluster.

nextPageToken : string​

This token allows you to get the next page of results for list requests.

If the number of results is larger than ListClusterHostsRequest.page_size, use the next_page_token as the value for the ListClusterHostsRequest.page_token query parameter in the next list request.

Each subsequent list request has its own next_page_token to continue paging through the results.

health : Health​

Aggregated health of the host. If the field has default value, it is not returned in the response.

subnetId : string​

ID of the subnet that the host belongs to.

assignPublicIp : bool​

Determines whether a public IP is assigned to the host.

Resources​

resourcePresetId : string​

ID of the preset for computational resources allocated to a host.
