Twitter live data mining using Spark streaming and Scala.

Want to work and learn live streaming data processing? Easiest way to create a twitter developer app and follow below code to ingest and store data in your AWS S3 for further analysis and processing with tools like Amazon EMR or Machine learning projects.

Install Trust app and click arrow button to switch to business related services, click “Job Mock Interviewer” –>then “AWS job” to connect me to learn deeper concepts of Spark/Scala/Java/AWS without any cost. You may also outsource tech screening interview process to me. Trust Business app is available only in India. Others please visit “About me” of this blog to get my linkedin contact.
