Elasticsearch-引导检查失败

Question

我正在尝试使用Flink 5.x Elasticsearch接收器连接器将数据插入到微型VM上托管的ES 5.2.1实例。

由于这是处于开发模式的微型VM，因此我无法使其启动以接受9300上的TransportClient远程客户端连接，而不会失败引导检查。

我已经尝试了以下设置，但无法启动（9200上的http客户端工作正常）

transport.publish_host: 0.0.0.0
transport.bind_host: 0.0.0.0
http.host: "xxx"
http.host: 169.117.72.167
network.host: 0.0.0.0
network.publish_host: 0.0.0.0

请注意，ES仅出于开发目的而在小型VM上运行，而我无权进行更改。此框上的文件描述符限制。

Answer 1

我能够通过使用以下自ES 5.2
Discovery.type以来可用的设置来做到这一点：单节点（https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-
checks.html
）

使用该设置启动ES节点后，便能够使用传输客户端从非localhost客户端进行连接，这以前是一个问题。
