Installing Solr service

Ranger uses Apache Solr service to store data. So, you must install Solr service on the cluster before the migration, if it is not installed already. You can do it through the Ambari UI.

Go to Services > Add Service on the Ambari UI.

The Choose Services window appears.
Select Infra Solr service in the wizard and click Next.
Follow the instructions to configure settings and advanced properties and install the service.
Click Deploy.
