Amazon Elastic MapReduce (EMR) is a true big data platform. It provides a managed Hadoop framework that can process a huge volume of data across dynamically scalable Amazon EC2 instances. It allows us to run popular distributed frameworks with it, such as Presto, Hive, Spark, and others. This is a short video about Amazon EMR: https://youtu.be/S6Ja55n-o0M.
Organizations use Hadoop for big data use cases, such as clickstream analysis, log analysis, predictive analytics, data transformation, data lake, and many more. Often, business users need to work with raw data that is stored in Hadoop, in our case Amazon EMR. There are multiple ways to connect Hadoop with Tableau, such as Presto, Hive, and more.
