Question

我正在尝试使用Apache Flume将推文保存到我的HDFS。我目前正在使用Hadoop和Flume的Cloudera图像。我正在关注Cloudera博客的教程，但我无法连接到Twitter API。

我收到以下错误：

我已将我的twitter API凭据复制到flume.conf（我已在光盘和网络用户界面中尝试过）。我还试图再次重新生成它们并复制那些新的，但它对我没有帮助。

我的pom.xml包含：

<dependency>
  <groupId>org.twitter4j</groupId>
  <artifactId>twitter4j-stream</artifactId>
  <version>3.0.5</version>
</dependency>

这意味着不应该是here所描述的问题。

我还通过命令设置系统时间：

sudo ntpdate pool.ntp.org

有没有人知道可能出现什么问题？非常感谢您提出任何建议和帮助。
