我是弹性搜索的新手，虽然有solr的经验......
我一直在尝试设置elasticsearch来运行一些测试，但是我在安装jdbc河时遇到了有趣的错误，请使用以下步骤：https://github.com/jprante/elasticsearch-river-jdbc/wiki/Quickstart
安装插件并启动elasticsearch后出现第一个错误，如下所示：

我谷歌搜索了一下，但找不到足够的东西来解释这里发生了什么。谁能告诉我我的安装有什么问题？一些遗漏的依赖项？
我使用的是0.90.2版。
答案 0 :(得分：1)
我怀疑您可能已将客户端配置为在端口9300上与REST API通信.REST API不在9300上运行，这是传输协议。
如果是这种情况，请尝试使用端口9200（HTTP端口）。
