Managed Service for Apache Spark optional Solr component

The Apache Solr optional component lets you deploy an open source enterprise search platform on Managed Service for Apache Spark clusters. This integration provides distributed search and indexing capabilities, hosting the Solr server and Web UI on port 8983 on the cluster master nodes.

By default, Solr stores index and transaction log files in HDFS. To persist your Solr files beyond the cluster lifecycle, you can specify a Cloud Storage path as the Solr home directory by setting the dataproc:solr.gcs.path cluster property when you install the component.

Install the component

Install the component when you create a Managed Service for Apache Spark cluster. Components can be added to clusters created with Managed Service for Apache Spark version 1.3 and later.

See Supported Managed Service for Apache Spark versions for the component version included in each Managed Service for Apache Spark image release.

Google Cloud console

1. In the Google Cloud console, open the Create cluster page.
2. Click Additional configuration to expand that section.
3. Edit Optional components.
4. In the panel that opens, select the checkbox for Solr, then click Save.

gcloud CLI

To create a Managed Service for Apache Spark cluster that includes the Solr component, use the gcloud dataproc clusters create cluster-name command with the --optional-components flag. The sample command below uses the optional properties flag to set a Cloud Storage path as the Solr home directory.

When creating the cluster, use gcloud dataproc clusters create command with the --enable-component-gateway flag, as shown below, to enable connecting to the Solr Web UI using the Component Gateway.

gcloud dataproc clusters create cluster-name \
    --region=region \
    --optional-components=SOLR \
    --enable-component-gateway \
    ... other flags

Add the --properties="dataproc:solr.gcs.path=gs://bucket-name/" cluster property to the gcloud dataproc clusters create command to set a Cloud Storage bucket where Solr documents will be stored (Solr home directory).

REST API

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

As part of your clusters.create request, you can:

1. Set the EndpointConfig.enableHttpPortAccess property to true to enable connecting to the Solr Web UI using the Component Gateway.
2. Set the "dataproc:solr.gcs.path=gs://bucket-name" cluster property in the SoftwareConfig.Component.properties field to set a Cloud Storage bucket where Solr documents will be stored (Solr home directory).
