Amazon EMR is a good place to run Apache Spark. You can quickly and easily create managed Spark clusters from the Amazon Web Services Management Console, Amazon Web Services CLI, or the Amazon EMR API. Additionally, you can leverage additional Amazon EMR features, including fast Amazon S3 connectivity using the Amazon EMR File System (EMRFS), integration with the Amazon EC2 Spot market and the Amazon Glue Data Catalog, and EMR Managed Scaling to add or remove instances from your cluster. Amazon Lake Formation brings fine-grained access control, while integration with Amazon Step Functions helps with orchestrating your data pipelines.
Features and benefits
Fast performance
EMR features Amazon EMR runtime for Apache Spark, a performance-optimized runtime environment for Apache Spark that is active by default on Amazon EMR clusters. Amazon EMR runtime for Apache Spark can be faster than clusters without the EMR runtime, and has 100% API compatibility with standard Apache Spark. This improved performance means your workloads run faster and saves you compute costs, without making any changes to your applications.
By using a directed acyclic graph (DAG) execution engine, Spark can create efficient query plans for data transformations. Spark also stores input, output, and intermediate data in-memory as resilient data frames, which allows for fast processing without I/O cost, boosting performance of iterative or interactive workloads.
Develop applications quickly and collaboratively
Apache Spark natively supports Java, Scala, SQL, and Python, which gives you a variety of languages for building your applications. Also, you can submit SQL or HiveQL queries using the Spark SQL module. In addition to running applications, you can use the Spark API interactively with Python or Scala directly in the Spark shell. Support for Apache Hadoop 3.0 in EMR 6.0 brings Docker container support to simplify managing dependencies. You can tune and debug your workloads in the EMR console which has an off-cluster, persistent Spark History Server.
Create diverse workflows
Apache Spark includes several libraries to help build applications for machine learning (MLlib), stream processing (Spark Streaming), and graph processing (GraphX). These libraries are tightly integrated in the Spark ecosystem, and they can be leveraged out of the box to address a variety of use cases. Additionally, you can use deep learning frameworks like Apache MXNet with your Spark applications. Integration with Amazon Step Functions enables you to add serverless workflow automation and orchestration to your applications.
Integration with Amazon EMR feature set
Submit Apache Spark jobs with the EMR Step API, use Spark with EMRFS to directly access data in S3, save costs using EC2 Spot capacity, use EMR Managed Scaling to dynamically add and remove capacity, and launch long-running or transient clusters to match your workload. You can also easily configure Spark encryption and authentication with Kerberos using an EMR security configuration. Additionally, you can use the Amazon Glue Data Catalog to store Spark SQL table metadata or use Amazon SageMaker with your Spark machine learning pipelines. EMR installs and manages Spark on Hadoop YARN, and you can also add other big data applications on your cluster. EMR with Apache Hudi lets you more efficiently manage change data capture (CDC) and helps with privacy regulations like China Personal Information Protection Law by simplifying record deletion.
Use cases
Stream processing
Consume and process real-time data from Amazon Kinesis or other data streams with Spark Streaming on EMR. Perform streaming analytics in a fault-tolerant way and write results to S3 or on-cluster HDFS.
Machine learning
Apache Spark on EMR includes MLlib for a variety of scalable machine learning algorithms, or you can use your own libraries. By storing datasets in-memory during a job, Spark has great performance for iterative queries common in machine learning workloads.
Interactive SQL
Use Spark SQL for low-latency, interactive queries with SQL or HiveQL. Spark on EMR can leverage EMRFS, so you can have ad hoc access to your datasets in S3.
