Cloud Dataproc Druid Component

You can install additional components when you create a Dataproc cluster using the Optional Components feature. This page describes the Druid component.

The Apache Druid component is an open source distributed OLAP data store. The Druid component installs Druid services on the Dataproc cluster master (Coordinator, Broker, and Overlord) and worker (Historical, Realtime and MiddleManager) nodes.

Install the component

Install the component when you create a Dataproc cluster. Components can be added to clusters created with Dataproc version 1.3 and later. The Druid component requires the installation of the Zookeeper component (as shown in the gcloud command-line tool example, below).

See Supported Cloud Dataproc versions for the component version included in each Dataproc image release.

gcloud command

To create a Dataproc cluster that includes the Druid component, use the gcloud dataproc beta clusters create cluster-name command with the --optional-components flag (using image version 1.3 or later).

gcloud beta dataproc clusters create cluster-name \
    --optional-components=DRUID,ZOOKEEPER \
    --image-version=1.3 \
  ... other flags

REST API

The Druid component can be specified through the Dataproc API using SoftwareConfig.Component as part of a clusters.create request.
