Error description

  • When the network.host parameter and
    discovery.zen.ping.unicast.hosts attribute in the IBM Process
    Federation Server server.xml file are configured by using a
    host name other than the IP address, the validation tool might
    report an error similar to the following errors:
     An unknown node joined the cluster.
     Node name:node2 Host name:bpm09.acme.com Port:9,300
     An unknown node joined the cluster.
     Node name:node2 Host name:bpm11.acme.com Port:9,300
    
    The following Elasticsearch node configured in the
    discovery.zen.ping.unicast.hosts attribute has not joined
    the cluster: Host name:bpm09.acme.com Port:9300
    
    If the node is running, check the system logs for connection
    issues. Check the SSL setting, the cluster name, and the
    passphrase definitions for this Elasticsearch node.
    

Local fix

  • Configure the network.host parameter and
    discovery.zen.ping.unicast.hosts attribute
    in the IBM Process Federation Server server.xml
    by using an IP address rather than host name.
    

Problem summary

  • The Elasticsearch client API might return the full host name or
    the short host name depending on the operating system. However,
    the Process Federation Server validation tool always assumes the
    short host name is returned, so an unknown node joined the
    cluster error is reported when the full host name is returned.
    

Problem conclusion

Temporary fix
