Статья создана

Retrieves a list of subclusters in the specified cluster.

HTTP request

GET https://dataproc.api.cloud.yandex.net/dataproc/v1/clusters/{clusterId}/subclusters

Path parameters

Parameter Description
clusterId

Required. ID of the Data Proc cluster to list subclusters in.

The maximum string length in characters is 50.

Query parameters

Parameter Description
pageSize

The maximum number of results per page to return. If the number of available results is larger than pageSize, the service returns a nextPageToken that can be used to get the next page of results in subsequent list requests. Default value: 100.

The maximum value is 1000.
pageToken

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

The maximum string length in characters is 100.
filter

A filter expression that filters subclusters listed in the response.

The expression must specify:

  1. The field name. Currently you can use filtering only on Subcluster.name field.
  2. An = operator.
  3. The value in double quotes ("). Must be 3-63 characters long and match the regular expression [a-z][-a-z0-9]{1,61}[a-z0-9]. Example of a filter: name=dataproc123_subcluster456.

The maximum string length in characters is 1000.

Response

HTTP Code: 200 - OK

Field Description
subclusters[] object

List of subclusters in the specified cluster.
subclusters[].
id		 string

ID of the subcluster. Generated at creation time.
subclusters[].
clusterId		 string

ID of the Data Proc cluster that the subcluster belongs to.
subclusters[].
createdAt		 string (date-time)

Creation timestamp.

String in RFC3339 text format.
subclusters[].
name		 string

Name of the subcluster. The name is unique within the cluster.

subclusters[].
role		 string

Role that is fulfilled by hosts of the subcluster.

  • MASTERNODE: The subcluster fulfills the master role.

    Master can run the following services, depending on the requested components:

    • HDFS: Namenode, Secondary Namenode
    • YARN: ResourceManager, Timeline Server
    • HBase Master
    • Hive: Server, Metastore, HCatalog
    • Spark History Server
    • Zeppelin
    • ZooKeeper

  • DATANODE: The subcluster is a DATANODE in a Data Proc cluster.

    DATANODE can run the following services, depending on the requested components:

    • HDFS DataNode
    • YARN NodeManager
    • HBase RegionServer
    • Spark libraries

  • COMPUTENODE: The subcluster is a COMPUTENODE in a Data Proc cluster.

    COMPUTENODE can run the following services, depending on the requested components:

    • YARN NodeManager
    • Spark libraries
subclusters[].
resources		 object

Resources allocated for each host in the subcluster.
subclusters[].
resources.
resourcePresetId		 string

ID of the resource preset for computational resources available to a host (CPU, memory etc.). All available presets are listed in the documentation.
subclusters[].
resources.
diskTypeId		 string

Type of the storage environment for the host. Possible values:

  • network-hdd - network HDD drive,
  • network-ssd - network SSD drive.

subclusters[].
autoscalingConfig		 object

Configuration for instance group based subclusters
subclusters[].
autoscalingConfig.
maxHostsCount		 string (int64)

Upper limit for total instance subcluster count.

Acceptable values are 1 to 100, inclusive.
subclusters[].
