Class FileBasedSeedHostsProvider

java.lang.Object

org.elasticsearch.discovery.FileBasedSeedHostsProvider

All Implemented Interfaces:

SeedHostsProvider

public class FileBasedSeedHostsProvider
extends Object
implements SeedHostsProvider

An implementation of SeedHostsProvider that reads hosts/ports from UNICAST_HOSTS_FILE. Each host/port that is part of the discovery process must be listed on a separate line. If the port is left off an entry, we default to the first port in the transport.port range. An example unicast hosts file could read: 67.81.244.10 67.81.244.11:9305 67.81.244.15:9400
