Creating a Scalable Amazon EMR Cluster on AWS in Minutes

Minutes to Scalable EMR Cluster on AWS

AWS EMR cluster

Spark helps you easily build up an Amazon EMR cluster to process and analyse data. This page covers Plan and Configure, Manage, and Clean Up.

This detailed guide to cluster setup:

Amazon EMR Cluster Configuration

Spark is used to launch an example cluster and run a PySpark script in the course. You must complete the “Before you set up Amazon EMR” exercises before starting.

While functioning live, the sample cluster will incur small per-second charges under Amazon EMR pricing, which varies per location. To avoid further expenses, complete the tutorial’s final cleaning steps.

The setup procedure has numerous steps:

Amazon EMR Cluster and Data Resources Configuration

This initial stage prepares your application and input data, creates your data storage location, and starts the cluster.

Setting Up Amazon EMR Storage:

Amazon EMR supports several file systems, but this article uses EMRFS to store data in an S3 bucket. EMRFS reads and writes to Amazon S3 in Hadoop.

This lesson requires a specific S3 bucket. Follow the Amazon Simple Storage Service Console User Guide to create a bucket.

You must create the bucket in the same AWS region as your Amazon EMR cluster launch. Consider US West (Oregon) us-west-2.

Amazon EMR bucket and folder names are limited. Lowercase letters, numerals, periods (.), and hyphens (-) can be used, but bucket names cannot end in numbers and must be unique across AWS accounts.

The bucket output folder must be empty.

Small Amazon S3 files may incur modest costs, but if you’re within the AWS Free Tier consumption limitations, they may be free.

Create an Amazon EMR app using input data:

Standard preparation involves uploading an application and its input data to Amazon S3. Submit work with S3 locations.

The PySpark script examines 2006–2020 King County, Washington food business inspection data to identify the top ten restaurants with the most “Red” infractions. Sample rows of the dataset are presented.

Create a new file called health_violations.py and copy the source code to prepare the PySpark script. Next, add this file to your new S3 bucket. Uploading instructions are in Amazon Simple Storage Service’s Getting Started Guide.

Download and unzip the food_establishment_data.zip file, save the CSV file to your computer as food_establishment_data.csv, then upload it to the same S3 bucket to create the example input data. Again, see the Amazon Simple Storage Service Getting Started Guide for uploading instructions.

“Prepare input data for processing with Amazon EMR” explains EMR data configuration.

Create an Amazon EMR Cluster:

Apache Spark and the latest Amazon EMR release allow you to launch the example cluster after setting up storage and your application. This may be done with the AWS Management Console or CLI.

Console Launch:

Launch Amazon EMR after login into AWS Management Console.

Start with “EMR on EC2” > “Clusters” > “Create cluster”. Note the default options for “Release,” “Instance type,” “Number of instances,” and “Permissions”.

Enter a unique “Cluster name” without <, >, $, |, or `. Install Spark from “Applications” by selecting “Spark”. Note: Applications must be chosen before launching the cluster. Check “Cluster logs” to publish cluster-specific logs to Amazon S3. The default destination is s3://amzn-s3-demo-bucket/logs. Replace with S3 bucket. A new ‘logs’ subfolder is created for log files.

Select your two EC2 keys under “Security configuration and permissions”. For the instance profile, choose “EMR_DefaultRole” for Service and “EMR_EC2_DefaultRole” for IAM.

Choose “Create cluster”.

The cluster information page appears. As the EMR fills the cluster, its “Status” changes from “Starting” to “Running” to “Waiting”. Console view may require refreshing. Status switches to “Waiting” when cluster is ready to work.

AWS CLI’s aws emr create-default-roles command generates IAM default roles.

Create a Spark cluster with aws emr create-cluster. Name your EC2 key pair –name, set –instance-type, –instance-count, and –use-default-roles. The sample command’s Linux line continuation characters () may need Windows modifications.

Output will include ClusterId and ClusterArn. Remember your ClusterId for later.

Check your cluster status using aws emr describe-cluster –cluster-id myClusterId>.

The result shows the Status object with State. As EMR deployed the cluster, the State changed from STARTING to RUNNING to WAITING. When ready, operational, and up, the cluster becomes WAITING.

Open SSH Connections

Before connecting to your operating cluster via SSH, update your cluster security groups to enable incoming connections. Amazon EC2 security groups are virtual firewalls. At cluster startup, EMR created default security groups: ElasticMapReduce-slave for core and task nodes and ElasticMapReduce-master for main.

Console-based SSH authorisation:

Authorisation is needed to manage cluster VPC security groups.

Launch Amazon EMR after login into AWS Management Console.

Select the updateable cluster under “Clusters”. The “Properties” tab must be selected.

Choose “Networking” and “EC2 security groups (firewall)” from the “Properties” tab. Select the security group link under “Primary node”.

EC2 console is open. Select “Edit inbound rules” after choosing “Inbound rules”.

Find and delete any public access inbound rule (Type: SSH, Port: 22, Source: Custom 0.0.0.0/0). Warning: The ElasticMapReduce-master group’s pre-configured rule that allowed public access and limited traffic to reputable sources should be removed.

Scroll down and click “Add Rule”.

Choose “SSH” for “Type” to set Port Range to 22 and Protocol to TCP.

Enter “My IP” for “Source” or a range of “Custom” trustworthy client IP addresses. Remember that dynamic IPs may need updating. Select “Save.”

When you return to the EMR console, choose “Core and task nodes” and repeat these steps to provide SSH access to those nodes.

Connecting with AWS CLI:

SSH connections may be made using the AWS CLI on any operating system.

Use the command: AWS emr ssh –cluster-id –key-pair-file <~/mykeypair.key>. Replace with your ClusterId and the full path to your key pair file.

After connecting, visit /mnt/var/log/spark to examine master node Spark logs.

The next critical stage following cluster setup and access configuration is phased work submission.
