Amazon EMR is a managed service from AWS for big data processing. EMR is used to run enterprise-scale data processing tasks using distributed computing. It breaks down tasks into smaller chunks and uses multiple computers for processing. It uses popular big data frameworks like Apache Hadoop and Apache Spark. EMR can be set up easily, enabling organizations to swiftly analyze and process large volumes of data without the hassle of managing servers.
The two primary options for storing data in Amazon EMR are Hadoop Distributed File System (HDFS) and Elastic MapReduce File System (EMRFS).
