cluster config generation using cluster config YAML file.

[iostreamdoth]

Description

Add cluster config generation from yaml file which is generated using gcloud dataproc clusters export command.

Use case / motivation

We are generating quite a lot of clusters using a cluster config which keeps on changing depending upon project to project. I wrote custom operator which reads yaml config and converts it to dict and then uses the same config to genreate cluster. Wondering if it will be useful if cluster config generator operator can accept a yaml config or can create a new operator.

Are you willing to submit a PR?

I do have a working code for converting yaml stored on gcs to dict.

Related Issues

There is no issue as such, it is a functionality which allows users to specify cluster config as yaml file.

config generator

DataprocCreateClusterOperatorClusterGenerator class is a deprecated and we are not adding new features to it.

I think we can extend DataprocCreateClusterOperator to accept the file path in cluster_config parameter like Cloud Build operator.

airflow/airflow/providers/google/cloud/operators/cloud_build.py

Lines 172 to 175 in d268016

	:param body: The build config with instructions to perform with CloudBuild.
	Can be a dictionary or path to a file type like YAML or JSON.
	See: https://cloud.google.com/cloud-build/docs/api/reference/rest/v1/projects.builds
	:type body: dict or string

you mean airflow.providers.google.cloud.operators.dataproc.DataprocCreateClusterOperator or you mean airflow.contrib.operators.dataproc_operator.DataprocClusterCreateOperator ? I thought this is going to be in providers package.

@iostreamdoth ClusterGenerator from providers is legacy/deprecated method to generate dataproc cluster configuration. You should use cluster_config parameter. For details, see:

airflow/airflow/providers/google/cloud/operators/dataproc.py

Lines 553 to 559 in 026ffe6

	"Passing cluster parameters by keywords to `{}` "
	"will be deprecated. Please provide cluster_config object using `cluster_config` parameter. "
	"You can use `airflow.dataproc.ClusterGenerator.generate_cluster` method to "

Got it, I got confused with the Operator name earlier.
Thanks @mik-laj
