Introduction to Big Data

Course description:

The production of data is expanding at an astounding pace. The explosion of accessible data through social media, the extensive use of web crawling, and the widespread availability of sensor data, have provided unprecedented amounts of data to organizations for collection and analysis. This two-day workshop explores drivers behind Big Data and uses cases across a wide variety of industries to illustrate the power of new technologies to harness Big Data and generate meaningful insights. Participants will be introduced to Hadoop and key-value data storage, the central components of the Big Data movement. These systems allow the distributed processing of very large data sets for structured and unstructured data.

During this course, participants will learn how Hadoop works with hands-on experiences using the Hadoop File Systems (HDFS) and MapReduce. Participants will also be introduced to several ecosystem components like HBase, Hive, Impala, and Spark used in Big Data reporting systems.

This is an introductory course in Big Data and Hadoop, but it will go beyond basics to introduce some technical components. It is appropriate for those that just want to learn more about Hadoop and Big Data and those that are looking to begin on a path to becoming a Hadoop developer.

Course outline:
