Dataproc optional Solr component

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

The Apache Solr component is an open source enterprise search platform. The Solr server and Web UI are available on port 8983 on the cluster's master node(s).

Persisting Solr files:By default, Solr writes and reads the index and transaction log files in HDFS . To persist Solr files, use 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 Dataproc cluster. Components can be added to clusters created with Dataproc version 1.3 and later.

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

gcloud command

To create a Dataproc 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:

Set the EndpointConfig.enableHttpPortAccess property to true to enable connecting to the Solr Web UI using the Component Gateway .
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).
