org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: unknown setting [discovery.zen.ping.multicast.enabled]

https://github.com/tk0miya/testing.elasticsearch/blob/master/src/testing/elasticsearch.py#L62

does not work with elasticsearch version 5.2, since this setting discovery.zen.ping.multicast.enabled has been removed for 5.2 version of elasticsearch.

Bump

Can we have a workaround writeup here until a fix has been made?

Here is the workaround:

from testing.elasticsearch import Elasticsearch as OldElasticsearchServer
from elasticsearch import Elasticsearch


# workaround https://github.com/tk0miya/testing.elasticsearch/issues/3
class ElasticsearchServer(OldElasticsearchServer):

    def initialize(self):
        super(ElasticsearchServer, self).initialize()
        self.DEFAULT_SETTINGS['boot_timeout'] = 60

        self.elasticsearch_yaml.pop('discovery.zen.ping.multicast.enabled')
        self.elasticsearch_yaml['discovery.zen.ping.unicast.hosts'] = ''
        self.elasticsearch_yaml['discovery.zen.minimum_master_nodes'] = 0


class TestApp(unittest.TestCase):

    @classmethod
    def setUpClass(cls):
        server = ElasticsearchServer()
        print(server.dsn())
        es = Elasticsearch(**server.dsn())
