Dataproc components
Stay organized with collections Save and categorize content based on your preferences.

Dataproc clusters feature the following types of components:

Installed components: Components that are installed in the image and activated when the cluster is created.
Optional components: Components that you select to install and use on your cluster when you create the cluster. Dataproc installs and activates optional components depending on the cluster image version as follows:
- 2.2 and earlier image versions: Optional components are automatically installed. Selected optional components are activated and non-selected optional components are uninstalled at cluster creation.
- 2.3 and later image versions: Optional components are installed during cluster creation. For more information, see Dataproc 2.3.x release versions.
To avoid increased cluster startup time for image versions 2.3 and later, create a custom image with optional components pre-installed. You can do this by running generate_custom_image.py with the --optional-components flag.
Initialization action components: Components installed on a cluster as part of an initialization action that you specify when you create a cluster.

Optional components are installed on a cluster before initialization actions are run on the cluster.

The Dataproc image version pages list the components and component types available in the latest Dataproc image releases.

Optional components have the following advantages over initialization actions used to install components:

Optional components are tested as compatible with specific Dataproc versions.
Optional components are enabled with a cluster creation parameter; initialization actions require a script.

Add optional components

Console

In the Google Cloud console, go to the Dataproc Create a cluster page.
Go to Create a cluster

The Set up cluster panel is selected.
In the Components section, under Optional components, select one or more components to install on your cluster.

Google Cloud CLI

To create a Dataproc cluster and install one or more optional components on the cluster, use the gcloud beta dataproc clusters create cluster-name command with the --optional-components flag.

gcloud dataproc clusters create CLUSTER_NAME \
  --optional-components=COMPONENT-NAME(s) \
  ... other flags

REST API

Optional components can be specified through the Dataproc API using SoftwareConfig.Component as part of a clusters.create request.
