Machine Learning Settings in Elasticsearch

You do not need to configure any settings to use machine learning. It is enabled by default.

General Machine Learning Settings

Set to true (default) to enable machine learning on the node.

If set to false in elasticsearch.yml, the machine learning APIs are disabled on the node. Therefore the node cannot open jobs, start datafeeds, or receive transport (internal) communication requests related to machine learning APIs. It also affects all Kibana instances that connect to this Elasticsearch instance; you do not need to disable machine learning in those kibana.yml files. For more information about disabling machine learning in specific Kibana instances, see Kibana Machine Learning Settings.

If you want to use machine learning features in your cluster, you must have set to true on all master-eligible nodes. This is the default behavior.

Set to true (default) to identify the node as a machine learning node.

If set to false in elasticsearch.yml, the node cannot run jobs. If set to true but is set to false, the setting is ignored and the node cannot run jobs. If you want to run jobs, there must be at least one machine learning node in your cluster.

On dedicated coordinating nodes or dedicated master nodes, disable the role.
