Course Overview:
Hadoop Development, Administration and BI Program is a one-stop course that introduces you to the domain of Hadoop development as well as gives you technical knowhow of the same and it is the most popular Big Data processing framework. Spark is a general-purpose distributed data processing engine that is suitable for use in a wide range of circumstances. On top of the Spark core data processing engine, there are libraries for SQL, machine learning, graph computation, and stream processing, which can be used together in an application.
