GET /clusters/{clusterName}/services

Lists all services registered in the cluster.

Request Parameters
name type description default
clusterName path n/a

Response Body
media type data type description
application/json ApiServiceList (JSON) List of services.

POST /clusters/{clusterName}/services

Creates a list of services.

There are typically two service creation strategies:

  1. The caller may choose to set up a new service piecemeal, by first creating the service itself (without any roles or configuration), and then create the roles, and then specify configuration.
  2. Alternatively, the caller can pack all the information in one call, by fully specifying the fields in the com.cloudera.api.model.ApiService object, with
    • service config and role type config, and
    • role to host assignment.

GET /clusters/{clusterName}/services/{serviceName}/metrics

This method has been deprecated. This endpoint is not supported as of v6. Use the timeseries API instead. To get all metrics for a service with the timeseries API use the query:

'select * where serviceName = $SERVICE_NAME'.

To get specific metrics for a service use a comma-separated list of the metric names as follows:

'select $METRIC_NAME1, $METRIC_NAME2 where serviceName = $SERVICE_NAME'.

For more information see the tsquery language documentation.

Fetch metric readings for a particular service.

By default, this call will look up all metrics available for the service. If only specific metrics are desired, use the metrics parameter.

By default, the returned results correspond to a 5 minute window based on the provided end time (which defaults to the current server time). The from and to parameters can be used to control the window being queried. A maximum window of 3 hours is enforced.

When requesting a "full" view, aside from the extended properties of the returned metric data, the collection will also contain information about all metrics available for the service, even if no readings are available in the requested window.

HDFS services that have more than one nameservice will not expose any metrics. Instead, the nameservices should be queried separately.

Request Parameters
name type description default

serviceName path The name of the service. n/a
from query Start of the period to query. n/a
metrics query Filter for which metrics to query. n/a

POST /clusters/{clusterName}/services/{serviceName}/commands/deployClientConfig

Deploy a service's client configuration.

The client configuration is deployed to the hosts where the given roles are running.

Added in v3: passing null for the role name list will deploy client configs to all known service roles. Added in v6: passing an empty role name list will deploy client configs to all known service roles.

In Cloudera Manager 5.3 and newer, client configurations are fully managed, meaning that the server maintains state about which client configurations should exist and be managed by alternatives, and the agents actively rectify their hosts with this state. Consequently, if this API call is made with a specific set of roles, Cloudera Manager will deactivate, from alternatives, any deployed client configs from any non-gateway roles that are not specified as arguments. Gateway roles are always preserved, and calling this API with an empty or null argument continues to deploy to all roles.

clusterName path n/a
serviceName path The service name. n/a
Request Body
media type data type description
application/json ApiRoleNameList (JSON) List of role names.
