Java使用TransportClient连接ES授权失败问题：missing authentication token for action [cluster

irpas 02-07 1446

背景

公司的一个项目TEST环境ES不需要授权、UAT环境使用x-pack做鉴权；这我看着官方文档写的代码不兼容了呀，也就出现了授权失败的问题；再加上我也是第一次遇到ES做鉴权的场景，以前公司直接就可以访问。

环境信息如下：

ElasticSearch版本：5.6.16x-pack版本：5.6.16

主要异常信息 org.elasticsearch.transport.RemoteTransportException: [Z2KL4U0][100.10.10.100:9300][cluster:monitor/nodes/liveness] Caused by: org.elasticsearch.ElasticsearchSecurityException: missing authentication token for action [cluster:monitor/nodes/liveness] 整个异常复现过程 1、参照官网使用TransportClient连接ES
