运行命令时：

storm jar target/crawlIndexer-1.0-SNAPSHOT.jar  org.apache.storm.flux.Flux --local es-injector.flux --sleep 86400000

我收到一条错误消息：

8710 [Thread-26-status-executor[4 4]] ERROR c.d.s.e.p.StatusUpdaterBolt - 
Can't connect to ElasticSearch

在浏览器中运行http://localhost:9200/时，ES 成功加载。Kibana 也连接到 ES。所以它一定只是从 StromCrawler 到 ElasticSearch 的连接。

可能是什么问题？

完整错误的片段：

也许我需要在 elasticsearch.yml 或 es-conf.yml 中修改一些东西？（它们都有默认设置）

通过玩（很多小时）让应用程序工作。

脚步：

  • 在 maven 文件中将 Storm-Crawler-Core 和 Storm-Crawler-Elastic-Search 恢复到 1.5 版。
  • 使用 Storm-Crawler-Elastic-Search 的 1.5 通量/yaml 配置文件版本
  • 使用弹性搜索 5.4.0
  • 使用 Kibana 5.4.0

您上面的错误消息提到 ElasticSearchConnection.java:104 因此您必须使用发布而不是主分支中的代码。确保 es conf 对应于相同的版本。您是否从 master 分支复制了 conf？下一个版本将有不同的地址格式
