class airflow.providers.google.cloud.operators.dataproc.PreemptibilityType[source]¶

Bases: enum.Enum

Contains possible Type values of Preemptibility applicable for every secondary worker of Cluster.

SPOT = 'SPOT'[source]¶

PREEMPTIBILITY_UNSPECIFIED = 'PREEMPTIBILITY_UNSPECIFIED'[source]¶

NON_PREEMPTIBLE = 'NON_PREEMPTIBLE'[source]¶

class airflow.providers.google.cloud.operators.dataproc.InstanceSelection[source]¶

Defines machines types and a rank to which the machines types belong.

Representation for google.cloud.dataproc.v1#google.cloud.dataproc.v1.InstanceFlexibilityPolicy.InstanceSelection.

Parameters

machine_types – Full machine-type names, e.g. “n1-standard-16”.
rank – Preference of this instance selection. Lower number means higher preference. Dataproc will first try to create a VM based on the machine-type with priority rank and fallback to next rank based on availability. Machine types and instance selections with the same priority have the same preference.

Bases: airflow.providers.google.cloud.operators.cloud_base.GoogleCloudBaseOperator

Create a new cluster on Google Cloud Dataproc.

The operator will wait until the creation is successful or an error occurs in the creation process.

If the cluster already exists and use_if_exists is True, then the operator will: - if cluster state is ERROR then delete it if specified and raise error - if cluster state is CREATING wait for it and then check for ERROR state - if cluster state is DELETING wait for it and then create new cluster

Please refer to https://cloud.google.com/dataproc/docs/reference/rest/v1/projects.regions.clusters

for a detailed explanation on the different parameters. Most of the configuration parameters detailed in the link are available as a parameter to this operator.
