NOTE: You are looking at documentation for an older release. For the latest information, see the current release documentation.
The functionality provided by the
discovery-file plugin is now available in
Elasticsearch without requiring a plugin. This plugin still exists to ensure
backwards compatibility, but it will be removed in a future version.
On installation, this plugin creates a file at
$ES_PATH_CONF/discovery-file/unicast_hosts.txt that comprises comments that
describe how to use it. It is preferable not to install this plugin and instead
to create this file, and its containing directory, using standard tools.
This plugin can be installed using the plugin manager:
sudo bin/elasticsearch-plugin install discovery-file
The plugin must be installed on every node in the cluster, and each node must be restarted after installation.
This plugin can be downloaded for offline install from https://artifacts.elastic.co/downloads/elasticsearch-plugins/discovery-file/discovery-file-6.8.20.zip.
The plugin can be removed with the following command:
sudo bin/elasticsearch-plugin remove discovery-file
The node must be stopped before removing the plugin.
