StormCrawler無法連接到ElasticSearch

Question

運行命令時：

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

我收到一條錯誤消息：

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

在瀏覽器中運行http：// localhost：9200 /時 ，ES成功加載。 Kibana還連接到ES。 因此，它必須僅僅是從StromCrawler到ElasticSearch的連接。

可能是什么問題？

也許我需要在elasticsearch.yml或es-conf.yml中進行修改？ （它們都有默認設置）

Answer 1

通過玩耍（許多小時）使應用程序正常工作。

腳步：

• 在maven文件中將Storm-Crawler-Core和Storm-Crawler-Elastic-Search恢復為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

上面的錯誤消息提到了ElasticSearchConnection.java:104，因此您必須使用發行版，而不是master分支中的代碼。 確保es conf對應於相同版本 。 您是否從master分支復制了conf？ 下一個版本的地址將具有不同的格式
