When specifying roles to be created, the names provided for each role must not conflict with the names that CM auto-generates for roles. Specifically, names of the form "--" cannot be used unless the is the same one CM would use. If CM detects such a conflict, the error message will indicate what is safe to use. Alternately, a differently formatted name should be used. Since API v6: The role name can be left blank to allow CM to generate the name.

getMetrics

ApiMetricList getMetrics(clusterName, roleName, serviceName, from, metrics, to, view)

Fetch metric readings for a particular role.

By default, this call will look up all metrics available for the role. 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 role, even if no readings are available in the requested window.

// Import classes:
//import com.cloudera.api.swagger.client.ApiClient;
//import com.cloudera.api.swagger.client.ApiException;

readRoleConfig

ApiConfigList readRoleConfig(clusterName, roleName, serviceName, view)

Retrieves the configuration of a specific role.
