Question

我正在尝试使用Java Bulk API在ElasticSearch中创建文档。我使用JSON文件作为批量输入。当我执行时，我得到以下异常：

Exception in thread "main" NoNodeAvailableException[None of the configured nodes are available: []]
at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:280)
at org.elasticsearch.client.transport.TransportClientNodesService.execute(TransportClientNodesService.java:197)

这是java代码。

要检查的事情：

检查您的群集名称是否与中定义的群集名称相同 elastic.yml
尝试使用索引名称创建索引（在您的情况下为'testindex'）来自任何REST客户端的PUT api （例如：AdvancedRestClient）http://localhost:9200/testindex（你的请求必须成功，即状态代码== 200）

使用上述PUT请求创建索引后运行程序。
