public class TribeService
extends AbstractLifecycleComponent<TribeService>

The tribe service holds a list of node clients connected to a list of tribe members, and uses their cluster state events to update this local node cluster state with the merged view of it.

The processSettings(org.elasticsearch.common.settings.Settings) method should be called before starting the node, so it will make sure to configure this current node properly with the relevant tribe node settings.

The tribe node settings make sure the discovery used is "local", but with no master elected. This means no write level master node operations will work (MasterNotDiscoveredException will be thrown), and state level metadata operations with automatically use the local flag.

The state merged from different clusters include the list of nodes, metadata, and routing table. Each node merged will have in its tribe which tribe member it came from. Each index merged will have in its settings which tribe member it came from. In case an index has already been merged from one cluster, and the same name index is discovered in another cluster, the conflict one will be discarded. This happens because we need to have the correct index name to propagate to the relevant cluster.
