Bases: airflow.models.BaseOperator

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.

Bases: airflow.models.BaseOperator

The base class for operators that launch job on DataProc.

Parameters

  • job_name (str) – The job name used in the DataProc cluster. This name by default is the task_id appended with the execution data, but can be templated. The name will always be appended with a random number to avoid name clashes.

  • cluster_name (str) – The name of the DataProc cluster.

  • dataproc_properties (dict) – Map for the Hive properties. Ideal to put in default arguments (templated)

  • dataproc_jars (list) – HCFS URIs of jar files to add to the CLASSPATH of the Hive server and Hadoop MapReduce (MR) tasks. Can contain Hive SerDes and UDFs. (templated)

  • gcp_conn_id (str) – The connection ID to use connecting to Google Cloud.

  • delegate_to (str) – The account to impersonate using domain-wide delegation of authority, if any. For this to work, the service account making the request must have domain-wide delegation enabled.

  • labels (dict) – The labels to associate with this job. 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 job.

  • region (str) – The specified region where the dataproc cluster is created.

  • job_error_states (set) – Job states that should be considered error states. Any states in this set will result in an error being raised and failure of the task. Eg, if the CANCELLED state should also be considered a task failure, pass in {'ERROR', 'CANCELLED'}. Possible values are currently only 'ERROR' and 'CANCELLED', but could change in the future. Defaults to {'ERROR'}.

  • impersonation_chain (Union[str, Sequence[str]]) – Optional service account to impersonate using short-term credentials, or chained list of accounts required to get the access_token of the last account in the list, which will be impersonated in the request. If set as a string, the account must grant the originating account the Service Account Token Creator IAM role. If set as a sequence, the identities from the list must grant Service Account Token Creator IAM role to the directly preceding identity, with first account from the list granting this role to the originating account (templated).

  • asynchronous (bool) – Flag to return after submitting the job to the Dataproc API. This is useful for submitting long running jobs and waiting on them asynchronously using the DataprocJobSensor

Variables

dataproc_job_id (str) – The actual “jobId” as submitted to the Dataproc API. This is useful for identifying or linking to the job in the Google Cloud Console Dataproc UI, as the actual “jobId” submitted to the Dataproc API is appended with an 8 character random string.

job_type =[source]
create_job_template(self)[source]

Initialize self.job_template with default values

_generate_job_template(self)[source]
execute(self, context)[source]
on_kill(self)[source]

Callback called when the operator is killed. Cancel any running job.

class airflow.providers.google.cloud.operators.dataproc.DataprocSubmitPigJobOperator(*, query: Optional[str] = None, query_uri: Optional[str] = None, variables: Optional[Dict] = None, **kwargs)[source]

Bases: airflow.providers.google.cloud.operators.dataproc.DataprocJobBaseOperator

Start a Pig query Job on a Cloud DataProc cluster. The parameters of the operation will be passed to the cluster.

It’s a good practice to define dataproc_* parameters in the default_args of the dag like the cluster name and UDFs.

default_args = {
    'cluster_name': 'cluster-1',
    'dataproc_pig_jars': [
        'gs://example/udf/jar/datafu/1.2.0/datafu.jar',
        'gs://example/udf/jar/gpig/1.2/gpig.jar'
    ]
}

You can pass a pig script as string or file reference. Use variables to pass on variables for the pig script to be resolved on the cluster or use the parameters to be resolved in the script as template parameters.

Example:

t1 = DataProcPigOperator(
        task_id='dataproc_pig',
        query='a_pig_script.pig',
        variables={'out': 'gs://example/output/{{ds}}'},
        dag=dag)

  • retry (google.api_core.retry.Retry) – A retry object used to retry requests. If None is specified, requests will not be retried.

  • timeout (float) – The amount of time, in seconds, to wait for the request to complete. Note that if retry is specified, the timeout applies to each individual attempt.

  • metadata (Sequence[Tuple[str, str]]) – Additional metadata that is provided to the method.

  • gcp_conn_id (str) – The connection ID to use connecting to Google Cloud.

  • impersonation_chain (Union[str, Sequence[str]]) – Optional service account to impersonate using short-term credentials, or chained list of accounts required to get the access_token of the last account in the list, which will be impersonated in the request. If set as a string, the account must grant the originating account the Service Account Token Creator IAM role. If set as a sequence, the identities from the list must grant Service Account Token Creator IAM role to the directly preceding identity, with first account from the list granting this role to the originating account (templated).

Submits a job to a cluster.

Parameters

  • project_id (str) – Required. The ID of the Google Cloud project that the job belongs to.

  • location (str) – Required. The Cloud Dataproc region in which to handle the request.

  • job (Dict) – Required. The job resource. If a dict is provided, it must be of the same form as the protobuf message Job

  • request_id (str) – Optional. A unique id used to identify the request. If the server receives two SubmitJobRequest requests with the same id, then the second request will be ignored and the first Job created and stored in the backend is returned. It is recommended to always set this value to a UUID.

  • impersonation_chain (Union[str, Sequence[str]]) – Optional service account to impersonate using short-term credentials, or chained list of accounts required to get the access_token of the last account in the list, which will be impersonated in the request. If set as a string, the account must grant the originating account the Service Account Token Creator IAM role. If set as a sequence, the identities from the list must grant Service Account Token Creator IAM role to the directly preceding identity, with first account from the list granting this role to the originating account (templated).

  • asynchronous (bool) – Flag to return after submitting the job to the Dataproc API. This is useful for submitting long running jobs and waiting on them asynchronously using the DataprocJobSensor

  • cancel_on_kill (bool) – Flag which indicates whether cancel the hook’s job or not, when on_kill is called

  • wait_timeout (int) – How many seconds wait for job to be ready. Used only if asynchronous is False

Bases: airflow.models.BaseOperator

Updates a cluster in a project.

Parameters

  • project_id (str) – Required. The ID of the Google Cloud project the cluster belongs to.

  • location (str) – Required. The Cloud Dataproc region in which to handle the request.

  • cluster_name (str) – Required. The cluster name.

  • cluster (Union[Dict, google.cloud.dataproc_v1beta2.types.Cluster]) –

    Required. The changes to the cluster.

    If a dict is provided, it must be of the same form as the protobuf message Cluster

  • update_mask (Union[Dict, google.protobuf.field_mask_pb2.FieldMask]) – Required. Specifies the path, relative to Cluster, of the field to update. For example, to change the number of workers in a cluster to 5, the update_mask parameter would be specified as config.worker_config.num_instances, and the PATCH request body would specify the new value. If a dict is provided, it must be of the same form as the protobuf message FieldMask

  • graceful_decommission_timeout (Union[Dict, google.protobuf.duration_pb2.Duration]) – Optional. Timeout for graceful YARN decommissioning. Graceful decommissioning allows removing nodes from the cluster without interrupting jobs in progress. Timeout specifies how long to wait for jobs in progress to finish before forcefully removing nodes (and potentially interrupting jobs). Default timeout is 0 (for forceful decommission), and the maximum allowed timeout is 1 day.

  • request_id (str) – Optional. A unique id used to identify the request. If the server receives two UpdateClusterRequest requests with the same id, then the second request will be ignored and the first google.longrunning.Operation created and stored in the backend is returned.

  • retry (google.api_core.retry.Retry) – A retry object used to retry requests. If None is specified, requests will not be retried.

  • timeout (float) – The amount of time, in seconds, to wait for the request to complete. Note that if retry is specified, the timeout applies to each individual attempt.

  • metadata (Sequence[Tuple[str, str]]) – Additional metadata that is provided to the method.

  • gcp_conn_id (str) – The connection ID to use connecting to Google Cloud.

  • impersonation_chain (Union[str, Sequence[str]]) – Optional service account to impersonate using short-term credentials, or chained list of accounts required to get the access_token of the last account in the list, which will be impersonated in the request. If set as a string, the account must grant the originating account the Service Account Token Creator IAM role. If set as a sequence, the identities from the list must grant Service Account Token Creator IAM role to the directly preceding identity, with first account from the list granting this role to the originating account (templated).
