无法从neo4j创建elasticsearch索引

我想在neo4j数据上创建弹性搜索索引。我使用https://github.com/neo4j-contrib/neo4j-elasticsearch和https://www.youtube.com/watch?v=SJLSFsXgOvA&ab_channel=AnmolAgrawal来创建neo4j的elasticsearch索引。无法从neo4j创建elasticsearch索引

但之后，即时通讯neo4j.log文件中获取低于错误。

如何解决这个错误或有任何其他方式来更新索引如果neo4j节点的属性值更改？

我猜一些凭证错误。 –

您使用AWS ElasticSearch吗？他们不允许连接到单个节点。我在其他地方（来自AWS团队）阅读： “查看日志，似乎'iscconfig.discovery.NodeChecker'试图自动发现并连接到群集的各个节点，亚马逊一直在努力改进服务功能，但不幸的是，此时AWS不允许客户端连接到群集的各个节点，而是可以使用URL“

”连接。您需要关闭Jest客户端中的节点发现： ClientConfig clientConfig = new ClientConfig.Builder("http://localhost:9200").discoveryEnabled(false)

见https://github.com/searchbox-io/Jest/blob/master/jest/README.md#node-discovery-through-nodes-api
