StormCrawler无法连接到ElasticSearch

Question

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还连接到ES。 因此，它必须仅仅是从StromCrawler到ElasticSearch的连接。

可能是什么问题？

也许我需要在elasticsearch.yml或es-conf.yml中进行修改？ （它们都有默认设置）

Answer 1

通过玩耍（许多小时）使应用程序正常工作。

脚步：

• 在maven文件中将Storm-Crawler-Core和Storm-Crawler-Elastic-Search恢复为1.5版。
• 使用了Storm-Crawler-Elastic-Search中的1.5flux / yaml配置文件版本
• 使用Elastic Search 5.4.0
• 使用Kibana 5.4.0

Answer 2

上面的错误消息提到了ElasticSearchConnection.java:104，因此您必须使用发行版，而不是master分支中的代码。 确保es conf对应于相同版本 。 您是否从master分支复制了conf？ 下一个版本的地址将具有不同的格式
