Answer 1

I was trying to create an uber jar with maven and ran in to this problem and I was able to solve the issue as follows.

Here is how I configured the shade plugin to include twitter4j to my uber jar.

org.apache.maven.plugins
maven-shade-plugin
2.4.2

    
        package
        
            shade
        
        

            
                
                    spark-streaming-twitter_2.10:spark-streaming-twitter_2.10
                    
                        **
                    
                
                
                    twitter4j-stream:twitter4j-stream
                    
                        **
                    
                
                
                    *:*
                    
                        META-INF/*.SF
                        META-INF/*.DSA
                        META-INF/*.RSA
                    
                
            
        
    

Hope this helps.
