When does class start/end?
Classes begin promptly at 9:00 am, and typically end at 5:00 pm.
This four-day hands-on training course delivers the key concepts and expertise developers need to use Apache Spark to develop high-performance parallel applications. Participants will learn how to use Spark SQL to query structured data and Spark Streaming to perform real-time processing on streaming data from a variety of sources. Developers will also practice writing applications that use core Spark to perform ETL processing and iterative algorithms. The course covers how to work with “big data” stored in a distributed file system, and execute Spark applications on a Hadoop cluster. After taking this course, participants will be prepared to face real-world challenges and build applications to execute faster decisions, better decisions, and interactive analysis, applied to a wide variety of use cases, architectures, and industries.

Eric was a superb instructor that effortlessly explained complex topics in a simple and a fun way.
The instructor is one of the best I believe.
He has a great sense of humor, and he can always explain hard questions with an easy way.
I hope I can learn other courses from him.
Thank you.
It was very pleasant experience in going through this training with Charles Hardin. It is truly amazing to see Charles passion in teaching and technology.
The combination of Eric's lecture and the class materials enabled me to learn and practice the concepts went over in this training course.
Joel is one of the best instructor to listen to and explain the way you expect from a specialist . He is the best in industry.
