Solr service management via ADCM

Konstantin Alpashkin

The ADCM UI provides actions to manage the Solr service and its components. For information on how to run service actions, refer to ADH service actions.

The actions available for the Solr service are listed in the table below.

Action Description

Check

Runs service-specific tests to check the health of the service and its components

Start

Starts the service. When you run this action, the option Apply configs from ADCM is available. If it is set to true, all service configurations defined in ADCM settings will be applied on the service startup. Otherwise, the service starts without applying configurations from ADCM

Stop

Stops the service

Restart

Restarts the service. When you run this action, the option Apply configs from ADCM is available. If it is set to true, all service configurations defined in ADCM settings will be applied during the service restart. Otherwise, the service restarts without applying configurations from ADCM

Remove

Removes the service from the cluster. This action should be used to remove already installed services. Whereas the delete control can be used to remove a non-mapped service (a service which components have not been distributed among cluster hosts)

Add Server(s)

Adds Solr Server components to your cluster. Running this action opens the component-host mapping interface where you can add new Solr Server components

Shrink Server(s)

Removes Solr Server components from your cluster. Running this action opens the component-host mapping interface where you can remove Solr Server components from specific hosts

Manage Ranger plugin

Enables or disables Ranger plugin for Solr

Update collection expiration

Updates the expiration time (the _expire_at_ field) for a specific Solr collection. When you run this action, the following options are available:

  • Collection name — the Solr collection to update.

  • Expire at — the timestamp string that sets the expiration time for documents indexed in Solr. For example, 2023-07-28T18:05:03.371Z.

  • Batch size — the number of documents to process per one batch.
