Custom plugins directory

edit

The plugins directory can be changed from the default by adding the following to the elasticsearch.yml config file:

path.plugins: /path/to/custom/plugins/dir

The default location of the plugins directory depends on which package you install.

Mandatory Plugins

edit

If you rely on some plugins, you can define mandatory plugins by adding plugin.mandatory setting to the config/elasticsearch.yml file, for example:

plugin.mandatory: mapper-attachments,lang-python

For safety reasons, a node will not start if it is missing a mandatory plugin.
