Hadoop Big Data Stack AMI | 24/7 Support by cloudimg

This is repackaged software with additional charges for 24/7 support and guaranteed 24hr response SLA.

Hadoop Big Data Stack Overview

Apache Hadoop is the industry-standard framework for distributed storage and processing of massive datasets. HDFS provides reliable distributed file storage across clusters. MapReduce enables parallel data processing at scale. YARN manages cluster resources and job scheduling. Scale from single servers to thousands of nodes. Fault-tolerant design handles failures automatically. Process petabytes of data. Open source Apache project.

Why Choose This Hadoop AMI?

Pre-configured Hadoop installation saves days of setup. HDFS, MapReduce, and YARN ready. Cluster configuration templates included. Production-ready security settings. JVM tuning applied. Storage optimized for EC2. Multiple Hadoop versions available on launch spanning multiple OS variants. All with 24/7 cloudimg support and guaranteed 24hr response SLA.

Pre-Configured Integration

Hadoop services configured for startup. HDFS NameNode and DataNode ready. YARN ResourceManager and NodeManager configured. SSH access port 22. Java runtime optimized. Configuration files in standard locations. Log aggregation enabled. systemd service management.

Key Features

HDFS Storage - distributed file system across nodes. Block replication for redundancy. Petabyte-scale capacity. High throughput reads. Write-once-read-many optimization. Rack awareness for data locality. NameNode manages metadata.

MapReduce Processing - parallel data processing framework. Map phase distributes work. Reduce phase aggregates results. Fault recovery for failed tasks. Data locality optimization. Job history tracking.

YARN Resource Management - cluster resource scheduler. Dynamic resource allocation. Multiple frameworks support. Container-based execution. Queue management. ApplicationMaster coordination. NodeManager resource monitoring.

Scalability - start small and scale horizontally. Add nodes to expand capacity. Linear performance scaling. Handle growing datasets without redesign. Elastic scaling on EC2.

Use Cases

Data Lakes - store raw data at scale. Schema-on-read flexibility. Historical data retention. Multi-format support (CSV, JSON, Parquet, Avro).

Log Processing - aggregate logs from distributed systems. Pattern analysis. Security event correlation. Real-time ingestion with batch processing.

ETL Pipelines - extract from multiple sources. Transform at scale. Load to data warehouses. Scheduled batch jobs. Data quality validation.

Machine Learning - train models on large datasets. Feature engineering at scale. Model scoring. Integration with Spark MLlib.

Analytics & Reporting - ad-hoc queries via Hive. Structured data with Pig. Business intelligence integration. Historical trend analysis.

Fault Tolerance & Reliability

Automatic failure detection and recovery. Block replication prevents data loss. Task retries on failures. Speculative execution for slow tasks. NameNode high availability. Checkpoint and journal for metadata protection.

Performance Optimization

Data locality reduces network transfer. In-memory caching where beneficial. Compression support (Snappy, LZO, Gzip). Combiner functions reduce shuffle data. Rack awareness for optimal placement.

Ecosystem Integration

Works with Hive for SQL queries. Pig for data flow scripting. HBase for NoSQL. Spark for in-memory processing. Sqoop for database import. Flume for log collection. Oozie for workflow scheduling.

Support Included

24/7 cloudimg support with 24hr response SLA. One hour average for critical issues. HDFS configuration, MapReduce jobs, YARN tuning, cluster expansion, performance optimization, troubleshooting. OS and Hadoop support. UK team.

FAQ

Q: Which Hadoop version included? A: Multiple Apache Hadoop versions available across Alma Linux 8, Ubuntu 20.04, Ubuntu 22.04.

Q: Can I add more nodes? A: Yes. Launch additional instances and join to cluster. cloudimg assists with configuration.

Q: How to submit MapReduce jobs? A: Use hadoop jar command or YARN API. Examples in /usr/local/hadoop/share/hadoop.

Q: Is high availability configured? A: Base configuration single NameNode. HA setup requires multiple nodes. cloudimg provides guidance.

Q: What file formats supported? A: Text, CSV, JSON, Parquet, Avro, ORC, SequenceFile. Custom InputFormat supported.

Q: How to monitor cluster? A: Web UIs on ports 8088 (YARN), 9870 (HDFS). Metrics via JMX. Integration with monitoring tools.
