Discovery configuration check
editDiscovery configuration check
editBy default, when Elasticsearch first starts up it will try and discover other nodes running on the same host. If no elected master can be discovered within a few seconds then Elasticsearch will form a cluster that includes any other nodes that were discovered. It is useful to be able to form this cluster without any extra configuration in development mode, but this is unsuitable for production because it’s possible to form multiple clusters and lose data as a result.
This bootstrap check ensures that discovery is not running with the default configuration. It can be satisfied by setting at least one of the following properties:
-
discovery.seed_hosts
-
discovery.seed_providers
-
cluster.initial_master_nodes
Note that you must remove cluster.initial_master_nodes
from the configuration of every node after the cluster has started for the
first time. Instead, configure discovery.seed_hosts
or
discovery.seed_providers
. If you do not need any discovery configuration, for
instance if running a single-node cluster, set discovery.seed_hosts: []
to
disable discovery and satisfy this bootstrap check.
