Hortonworks教程生成失败，sun.security.provider.certpath.SunCertPathBuilderException

Question

我试图从“REALTIME事件处理HIFOOP，NIFI，KAFKA和风暴”构建“流模拟器”Hortonworks教程特别是从它的“实验室0：使用APACHE NIFI的入住，路线和土地实时活动“。

http://hortonworks.com/hadoop-tutorial/realtime-event-processing-nifi-kafka-storm/#stream-simulator-lab0

为了给你粗略的概念，这是什么，这里从Hortoworks页面描述：“流模拟器是一个轻量级的框架，其产生的卡车事件数据模拟器使用纽约市的卡车路线（KML ），其中定义了具有经度和纬度信息的驾驶员道路路径 模拟器使用Akka来简化并发性，消息传递和继承，它具有两个普通旧Java对象（PO​​JOS），一个用于卡车，另一个用于生成事件的驱动程序。

当我尝试建立模拟器直接从最新的Hortonworks沙盒（HDP 2.4）通过构建Maven的报告结束这个错误：

[ERROR] Failed to execute goal on project storm-kafka-0.8-plus:

unable to find valid certification path to requested target 

更详细的（Maven的-e）揭示了这些错误的详细信息：

...

任何想法如何解决这个问题？请帮忙！

更新：接下来生成错误

固定证书有问题之后，我现在有一个错误：

你的Maven插件尝试连接到HTTPS远程仓库，即https://clojars.org/repo/

您可以使用此帖子的解决方案之一：

Problems using Maven and SSL behind proxy

我推荐的解决方案是：

（步骤可以浏览器之间会发生变化）

• 使用浏览器（使用Chrome）去https://clojars.org/repo/
• 点击锁图标，然后选择“详细信息“并单击”查看证书“
• 转到”详细信息“选项卡并选择”复制到文件“
• 选择类型“Base 64 X.509（。CER）”，并保存到某个地方

• 现在打开一个命令提示符，然后键入（使用自己的路径）：

  keytool -import -file C:\temp\mavenCert.cer -keystore C:\temp\mavenKeystore

• 现在，您可以用参数

  -Djavax.net.ssl.trustStore=C:\temp\mavenKeystore再次运行该命令

• linux下使用绝对路径

  现在

可以运行Maven作为构建：

/root/maven/bin/mvn clean package -Djavax.net.ssl.trustStore=C:\temp\mavenKeystore
