The field of Big Data is exploding everyday with new software tools and technologies enabling us to answer questions that we may not have been able to, even a few years ago. Its impact has been felt in almost every sphere of life, from transportation, health, education, commerce, communications and politics. Hadoop has probably emerged as one of the most popular framework that enables huge data to be stored and processed. The tools that have been developed around Hadoop like Pig, Hive, Sqoop, Oozie, Flume, HBase, and Spark; with its ability to process streaming data and machine learning algorithms applied on massive data, is becoming the standard framework that developers want to learn and work with. This course will cover in detail various aspects of how Hadoop works along with introduction to Spark.
