The Amazon EMR runtime for Apache Spark is a performance-optimized runtime for Apache Spark that’s 100% API suitable with open-source Apache Spark. With Amazon EMR launch 6.9.0, the EMR runtime for Apache Spark helps equal Spark model 3.3.0.
With Amazon EMR 6.9.0, now you can run your Apache Spark 3.x purposes sooner and at decrease value with out requiring any adjustments to your purposes. In our efficiency benchmark exams, derived from TPC-DS efficiency exams at 3 TB scale, we discovered the EMR runtime for Apache Spark 3.3.0 supplies a 3.5 occasions (utilizing whole runtime) efficiency enchancment on common over open-source Apache Spark 3.3.0.
On this submit, we analyze the outcomes from our benchmark exams working a TPC-DS software on open-source Apache Spark after which on Amazon EMR 6.9, which comes with an optimized Spark runtime that’s suitable with open-source Spark. We stroll by means of an in depth value evaluation and at last present step-by-step directions to run the benchmark.
To guage the efficiency enhancements, we used an open-source Spark efficiency check utility that’s derived from the TPC-DS efficiency check toolkit. We ran the exams on a seven-node (six core nodes and one main node) c5d.9xlarge EMR cluster with the EMR runtime for Apache Spark, and a second seven-node self-managed cluster on Amazon Elastic Compute Cloud (Amazon EC2) with the equal open-source model of Spark. We ran each the exams with information in Amazon Easy Storage Service (Amazon S3).
Dynamic Useful resource Allocation (DRA) is a good function to make use of for various workloads. Nonetheless, for a benchmarking train the place we evaluate two platforms purely on efficiency, and check information volumes don’t change (3 TB in our case), we imagine it’s finest to keep away from variability to be able to run an apples-to-apples comparability. In our exams in each open-source Spark and Amazon EMR, we disabled DRA whereas working the benchmarking software.
The next desk exhibits the full job runtime for all queries (in seconds) within the 3 TB question dataset between Amazon EMR model 6.9.0 and open-source Spark model 3.3.0. We noticed that our TPC-DS exams had a complete job runtime on Amazon EMR on Amazon EC2 that was 3.5 occasions sooner than that utilizing an open-source Spark cluster of the identical configuration.
The per-query speedup on Amazon EMR 6.9 with and with out the EMR runtime for Apache Spark is illustrated within the following chart. The horizontal axis exhibits every question within the 3 TB benchmark. The vertical axis exhibits the speedup of every question because of the EMR runtime. Notable efficiency features are over 10 occasions sooner for TPC-DS queries 24b, 72, 95, and 96.
The efficiency enhancements of the EMR runtime for Apache Spark instantly translate to decrease prices. We have been in a position to notice a 67% value financial savings working the benchmark software on Amazon EMR as compared with the fee incurred to run the identical software on open-source Spark on Amazon EC2 with the identical cluster sizing resulting from diminished hours of Amazon EMR and Amazon EC2 utilization. Amazon EMR pricing is for EMR purposes working on EMR clusters with EC2 cases. The Amazon EMR worth is added to the underlying compute and storage costs equivalent to EC2 occasion worth and Amazon Elastic Block Retailer (Amazon EBS) value (if attaching EBS volumes). Total, the estimated benchmark value within the US East (N. Virginia) Area is $27.01 per run for the open-source Spark on Amazon EC2 and $8.82 per run for Amazon EMR.
|Benchmark Job||Runtime (Hour)||Estimated Price||Complete EC2 Occasion||Complete vCPU||Complete Reminiscence (GiB)||Root Machine (Amazon EBS)|
Open-source Spark on Amazon EC2

|0.63||$8.82||7||252||504||20 GiB gp2|
The next is the fee breakdown for the open-source Spark on Amazon EC2 job ($27.01):
- Complete Amazon EC2 value – (7 * $1.728 * 2.23) = (variety of cases * c5d.9xlarge hourly fee * job runtime in hour) = $26.97
- Amazon EBS value – ($0.1/730 * 20 * 7 * 2.23) = (Amazon EBS per GB-hourly fee * root EBS dimension * variety of cases * job runtime in hour) = $0.042
The next is the fee breakdown for the Amazon EMR on Amazon EC2 job ($8.82):
- Complete Amazon EMR value – (7 * $0.27 * 0.63) = ((variety of core nodes + variety of main nodes)* c5d.9xlarge Amazon EMR worth * job runtime in hour) = $1.19
- Complete Amazon EC2 value – (7 * $1.728 * 0.63) = ((variety of core nodes + variety of main nodes)* c5d.9xlarge occasion worth * job runtime in hour) = $7.62
- Amazon EBS value – ($0.1/730 * 20 GiB * 7 * 0.63) = (Amazon EBS per GB-hourly fee * EBS dimension * variety of cases * job runtime in hour) = $0.012
Arrange OSS Spark benchmarking
Within the following sections, we offer a quick define of the steps concerned in organising the benchmarking. For detailed directions with examples, discuss with the GitHub repo.
For our OSS Spark benchmarking, we use the open-source device Flintrock to launch our Amazon EC2-based Apache Spark cluster. Flintrock supplies a fast solution to launch an Apache Spark cluster on Amazon EC2 utilizing the command line.
Full the next prerequisite steps:
- Have Python 3.7.x or above.
- Have Pip3 22.2.2 or above.
- Add the Python bin listing to your surroundings path. The Flintrock binary will probably be put in on this path.
aws configureto configure your AWS Command Line Interface (AWS CLI) shell to level to the benchmarking account. Seek advice from Fast configuration with aws configure for directions.
- Have a key pair with restrictive file permissions to entry the OSS Spark main node.
- Create a brand new S3 bucket in your check account if wanted.
- Copy the TPC-DS supply information as enter to your S3 bucket.
- Construct the benchmark software following the steps offered in Steps to construct spark-benchmark-assembly software. Alternatively, you possibly can obtain a pre-built spark-benchmark-assembly-3.3.0.jar in order for you a Spark 3.3.0-based software.
Deploy the Spark cluster and run the benchmark job
Full the next steps:
- Set up the Flintrock device by way of pip as proven in Steps to setup OSS Spark Benchmarking.
- Run the command flintrock configure, which pops up a default configuration file.
- Modify the default
config.yamlfile primarily based in your wants. Alternatively, copy and paste the config.yaml file content material to the default configure file. Then save the file to the place it was.
- Lastly, launch the 7-node Spark cluster on Amazon EC2 by way of Flintrock.
This could create a Spark cluster with one main node and 6 employee nodes. In the event you see any error messages, double-check the config file values, particularly the Spark and Hadoop variations and the attributes of download-source and the AMI.
The OSS Spark cluster doesn’t include YARN useful resource supervisor. To allow it, we have to configure the cluster.
- Obtain the yarn-site.xml and enable-yarn.sh recordsdata from the GitHub repo.
- Substitute <non-public ip of main node> with the IP tackle of the first node in your Flintrock cluster.
You may retrieve the IP tackle from the Amazon EC2 console.
- Add the recordsdata to all of the nodes of the Spark cluster.
- Run the enable-yarn script.
- Allow Snappy help in Hadoop (the benchmark job reads Snappy compressed information).
- Obtain the benchmark utility software JAR file spark-benchmark-assembly-3.3.0.jar to your native machine.
- Copy this file to the cluster.
- Log in to the first node and begin YARN.
- Submit the benchmark job on the open-source Spark cluster as proven in Submit the benchmark job.
