Apache Spark Single-Node Cluster

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

Overview

Apache Spark is the open source unified analytics engine for large-scale data processing. This AMI delivers Spark 4 fully installed and configured as a single-node standalone cluster on EC2, giving data engineers and small teams a working analytics engine without cluster orchestration overhead, Kubernetes dependencies, or managed-service lock-in. Submit your first spark-submit job or PySpark session within minutes of launch - not hours of configuration.

Why This AMI Over Alternatives

Unlike managed services that add cluster spin-up latency and per-cluster pricing, this image gives you full root access to a production-grade Spark installation on a single instance you control. There is no vendor lock-in beyond EC2, no orchestration layer to manage, and no multi-node complexity for workloads that fit a single powerful instance. For dev/test environments, proof-of-concept pipelines, or cost-sensitive production workloads, you get predictable compute costs with expert support included.

Application Stack

• Apache Spark 4 with the standalone cluster manager
• Spark master and Spark worker running as systemd services under a dedicated unprivileged spark user (automatic restart on failure, no external orchestrator needed)
• Java 17 providing the JVM runtime for every Spark process
• Python 3 installed for PySpark
• spark-submit, spark-sql, spark-shell, and pyspark CLI tools ready to use immediately

AWS Integrations

This Spark image works with core AWS data services:

• Amazon S3 - Read and write data directly from S3 buckets for scalable, durable storage of input datasets, intermediate results, and output files. Use S3 as your data lake layer without managing HDFS.
• Amazon EBS - The dedicated data volume leverages EBS for independently resizable, encrypted storage. Enable EBS encryption to protect Spark worker data, SQL warehouse contents, and daemon logs at rest.
• AWS IAM - Attach IAM instance profiles to control access to S3 buckets, DynamoDB tables, and other AWS resources without embedding credentials in your Spark jobs.

Ready to Use

The Spark distribution, configuration, systemd units, and standalone cluster are all in place at boot. The master web UI is served on port 8080, showing the cluster state, workers, and every running or completed application. Submit your first job with spark-submit or start an interactive PySpark session immediately.

Security and Hardening

• Spark processes run under a dedicated unprivileged user - not root
• No passwords or shared credentials baked into the image
• Supports EBS encryption at rest for the data volume
• Recommended deployment behind a security group restricting port8080 (master UI) and port 7077 (master RPC) to trusted CIDR ranges only
• cloudimg support can assist with enabling TLS for master-worker communication and configuring Spark authentication
• On first boot, a one-shot service writes a non-secret information file and marks itself complete - no secrets are generated or stored

Dedicated Data Volume

A separate, independently resizable EBS data volume holds the Spark worker work directory, the SQL warehouse, and daemon logs. This prevents disk-full failures during large shuffles or extended job runs by keeping cluster data isolated from the operating system disk. Resize the volume as your workloads grow without reprovisioning the instance.

Example Use Case: Nightly ETL Pipeline Development

A data engineer prototyping a nightly ETL pipeline reads raw CSV or Parquet files from an S3 bucket, transforms them with PySpark, and writes cleansed output back to S3. The single-node cluster handles datasets up to hundreds of gigabytes on memory-optimized instances. Once validated, the same spark-submit scripts can be promoted to a multi-node cluster with minimal changes.

Additional Use Cases

• Large-scale batch data processing and ETL
• Interactive analytics and ad hoc SQL over large datasets
• Data engineering pipeline development and testing
• Machine learning feature engineering
• Proof-of-concept clusters before scaling to multi-node deployments
