You can now easily enable encryption for data at-rest and in-transit for Apache Spark, Apache Tez, and Apache Hadoop MapReduce on Amazon EMR. For encryption at-rest, you can encrypt data stored in Amazon S3 with the EMR File System (EMRFS) and data stored on your Amazon EMR cluster in the local file system on each node and the Hadoop Distributed File System (HDFS). For encryption in-transit, Amazon EMR will enable the open-source encryption features for Apache Spark, Apache Tez, and Apache Hadoop MapReduce.
