When does class start/end?
Classes begin promptly at 9:00 am, and typically end at 5:00 pm.
Apache Hive makes transformation and analysis of complex, multi-structured data scalable in Hadoop. Apache Impala enables real-time interactive analysis of the data stored in Hadoop using a native SQL environment. Together, they make multi-structured data accessible to analysts, database administrators, and others without Java programming expertise.
Prerequisites
This course is designed for data analysts, business intelligence specialists, developers, system architects, and database administrators. Some knowledge of SQL is assumed, as is basic Linux command-line familiarity. Prior knowledge of Apache Hadoop is not required.

Instructor was well?prepared and explained topics in much detail. Was also very responsive to questions asked by the audience.
Have been working in Cloudera for several months now, but haven't completely understood the animals and when to use as well as how things are working in the background. This class answered those questions.
Eric has been great at explaining and guiding the course. He is very knowledgeable and able to help tie the topics and concepts shared in the class back to our real life use cases.
Joel was great and handled our questions with great knowledge and professionalism.
Not every topic applied to my job but many topics applied. Joel spent a lot of time explaining how processing worked with the different tools which was also valuable!
