Resource: Cluster

Describes the identifying information, config, and status of a cluster of Compute Engine instances.

JSON representation 
{
  "projectId": string,
  "clusterName": string,
  "config": {
    object (ClusterConfig)
  },
  "labels": {
    string: string,
    ...
  },
  "status": {
    object (ClusterStatus)
  },
  "statusHistory": [
    {
      object (ClusterStatus)
    }
  ],
  "clusterUuid": string,
  "metrics": {
    object (ClusterMetrics)
  }
}
Fields
projectId

string

Required. The Google Cloud Platform project ID that the cluster belongs to.
clusterName

string

Required. The cluster name. Cluster names within a project must be unique. Names of deleted clusters can be reused.
config

object (ClusterConfig)

Required. The cluster config. Note that Dataproc may set default values, and values may change when clusters are updated.
labels

map (key: string, value: string)

Optional. The labels to associate with this cluster. Label keys must contain 1 to 63 characters, and must conform to RFC 1035. Label values may be empty, but, if present, must contain 1 to 63 characters, and must conform to RFC 1035. No more than 32 labels can be associated with a cluster.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
status

object (ClusterStatus)

Output only. Cluster status.
statusHistory[]

object (ClusterStatus)

Output only. The previous cluster status.
clusterUuid

string

Output only. A cluster UUID (Unique Universal Identifier). Dataproc generates this value when it creates the cluster.
metrics

object (ClusterMetrics)

Output only. Contains cluster daemon metrics such as HDFS and YARN stats.

Beta Feature: This report is available for testing purposes only. It may be changed before final release.

ClusterStatus

The status of a cluster and its instances.

JSON representation 
{
  "state": enum (State),
  "detail": string,
  "stateStartTime": string,
  "substate": enum (Substate)
}
Fields
state

enum (State)

Output only. The cluster's state.
detail

string

Output only. Optional details of cluster's state.
stateStartTime

string (Timestamp format)

Output only. Time when this state was entered (see JSON representation of Timestamp).

A timestamp in RFC3339 UTC "Zulu" format, accurate to nanoseconds. Example: "2014-10-02T15:01:23.045123456Z".
substate

enum (Substate)

Output only. Additional state information that includes status reported by the agent.

State

The cluster state.

Enums
UNKNOWN The cluster state is unknown.
CREATING The cluster is being created and set up. It is not ready for use.
RUNNING The cluster is currently running and healthy. It is ready for use.
ERROR The cluster encountered an error. It is not ready for use.
DELETING The cluster is being deleted. It cannot be used.
UPDATING The cluster is being updated. It continues to accept and process jobs.

Substate

The cluster substate.

Enums
UNSPECIFIED The cluster substate is unknown.
UNHEALTHY

The cluster is known to be in an unhealthy state (for example, critical daemons are not running or HDFS capacity is exhausted).

Applies to RUNNING state.
STALE_STATUS

The agent-reported status is out of date (may occur if Dataproc loses communication with Agent).

Applies to RUNNING state.

ClusterMetrics

Contains cluster daemon metrics, such as HDFS and YARN stats.

Beta Feature: This report is available for testing purposes only. It may be changed before final release.

JSON representation 
{
  "hdfsMetrics": {
    string: string,
    ...
  },
  "yarnMetrics": {
    string: string,
    ...
  }
}
Fields
hdfsMetrics

map (key: string, value: string (int64 format))

The HDFS metrics.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
yarnMetrics

map (key: string, value: string (int64 format))

The YARN metrics.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
