Cloudera Enterprise and Hadoop Overview

Cloudera Enterprise and Hadoop

• Cloudera's Hadoop solution aims to make large-scale data management fast, easy, and secure.
• Hadoop provides a central repository for unlimited data, with unified access across various frameworks.
• Cloudera enhances Hadoop with superior performance, simplified management, and compliant security.

Cloudera's Hadoop Management Suite

• Cloudera Manager is a comprehensive administration tool enabling zero-downtime administration for Apache Hadoop.
• Unique features include unified configuration, management, and monitoring across all Hadoop services.
• Online installation and upgrades are possible.
• Direct connection to Cloudera support is available.
• Third-party extensibility is a key component.

Spark Support and Integration

• Cloudera is a leading provider of Spark support, with more customers using Spark than competitors.
• Installations range from small to large deployments (a few nodes to 1000+.
• Cloudera is an early adopter and first Hadoop vendor to support Spark, actively developing and deploying Spark since early 2014.
• Cloudera and Intel have a combined 24+ developers working on Spark, with 4 committers.
• Integrated with other Cloudera components such as Cloudera Manager, Sentry, and Navigator.

KUDU: A New Storage Engine

• KUDU is a new storage engine designed for structured data (tables), eliminating the dependency on HDFS.
• It uses a columnar store for optimized data access.
• KUDU is mutable; meaning, it supports insertion, updates, deletions, and scans.
• Written in C++, Apache-licensed, and currently in beta.
• KUDU enables fast analytics on large datasets.

KUDU Use Cases

• KUDU is well-suited for scenarios requiring simultaneous sequential and random data access.
• Ideal for simplified data ingestion processes.
• Necessary when data updates are essential, such as with time-series data or streaming.
• Examples include time series data, streaming data, and online reporting.

Adaptive Data Model Management

• Cloudera's Navigator Optimizer streamlines data warehouse and Hadoop cluster usage, driving optimizations for reduced costs and better performance.
• Capabilities include schema and workload profiling, data model discovery, optimization guidance, and (future) automation.

Cisco Integration for IoT

• Cloudera integrates with Cisco's Big Data Analytics Platform, enabling ingesting and analyzing IoT data.
• Data is used for real-time Spark Streaming Analytics.
• Data is stored in, or written back into Kafka for further processing and application layer integration.

Enterprise Data Platform Architecture

• Cloudera provides an architecture for enterprise data platforms.
• Real-world use cases include preventative maintenance and improvement in traveler safety and airport efficiency.

Case Study: Smart Buildings Preventive Maintenance

• Using IoT sensors, Cloudera on Azure captures, secures, and correlates data from escalators, elevators, and baggage carousels to improve passenger safety.
  • This data allows for identifying and fixing potential equipment problems before they cause downtime.

Case Study: Smart Cities

• Cloudera helps smart cities manage snow and ice effectively, managing inclement weather road management in real-time.
• The system leverages weather response, real-time data, and sensor information from vehicles (e.g., salt trucks) for automatic vehicle locations.
  • Cities aggregate large datasets (15-20 million records daily) and process millions of records per second.
