Steve McPherson presented on Amazon EMR (Elastic MapReduce) at the Facebook Presto Meetup on March 19, 2015. Amazon EMR makes cluster management easy by handling setup and configuration, node monitoring and replacement, log aggregation, and integration with CloudWatch and Spot instances. Amazon EMR supports various big data frameworks like MapReduce, Spark, Hive, Pig, Presto and data stores like Amazon S3. It allows running different clusters optimized for different workloads like Hive/Pig, Presto or Spark.
