我构建了一个Uber Jar来运行一个简单的Spark Streaming Application,它会因以下错误而失败:
java.lang.NoSuchMethodError: twitter4j.TwitterStream.addListener(Ltwitter4j/StreamListener;)
我认为Uber jar可能不包含该类,但是该类存在:
user@someMachine~/somedir$ jar tvf target/your-project-0.0.1-SNAPSHOT-jar-with-dependencies.jar | grep twitter4j/TwitterStream.class
1064 Tue Jun 23 19:27:48 UTC 2015 twitter4j/TwitterStream.class
然后我认为twitter4j-stream
使用的版本4.0.4
是spark-streaming-twitter_2.10
版本1.6.0-cdh5.8.0
的依赖关系,可能不包含该类的方法AddListener
TwitterStream
但确实如此:http://twitter4j.org/oldjavadocs/4.0.4/index.html
我终于尝试将jar添加到类路径但遇到了同样的错误。除了尝试使用不同的工具进行构建之外,我不确定从何处开始。
有什么想法?这是pom.xml
