What is Hadoop?
Apache Hadoop is an open source
platform for data storage and processing
that is…
 Scalable
 Fault tolerant
 Distributed
CORE HADOOP SYSTEM COMPONENTS
Hadoop Distributed
File System (HDFS)
MapReduce
Self-Healing, High
Bandwidth Clustered
Storage
Provides storage and computation
in a single, scalable system.
Distributed Computing
Framework
Why Use Hadoop?
Move beyond rigid legacy frameworks.
Hadoop handles any data
type, in any quantity.
Hadoop grows with your
business.
 Structured, unstructured
 Schema, no schema
Hadoop helps you derive
the complete value of all
your data.
 No vendor lock-in
 Proven at petabyte scale
 High volume, low volume
 Capacity and performance
grow simultaneously
 All kinds of analytic
applications
 Leverages commodity
hardware to mitigate costs
1
Hadoop is 100% Apache®
licensed and open source.
2
 Community development
 Rich ecosystem of related
projects
3
 Drives revenue by extracting
value from data that was
previously out of reach
 Controls costs by storing data
more affordably than any
other platform
The Need for CDH
1. The Apache Hadoop ecosystem is complex
– Many different components – lots of moving parts
– Most companies require more than just HDFS and MapReduce
– Creating a Hadoop stack is time-consuming and requires specific expertise
• Component and version selection
• Integration (internal & external)
• System test w/end-to-end workflows
2. Enterprises consume software in a certain way

The Need for CDH
A set of open source components,
HDFS – Distributed, scalable, fault tolerant file system
MapReduce – Parallel processing framework for large
data sets
Apache Hive – SQL-like language and metadata
repository
Apache Pig – High level language for expressing data
analysis programs
Apache HBase – Hadoop database for random, realtime read/write access
Apache Oozie – Server-based workflow engine for
Hadoop activities
Apache Zookeeper – Highly reliable distributed
coordination service
Apache Sqoop – Integrating Hadoop with RDBMS
Apache Flume – Distributed service for collecting and
aggregating log and event data
Fuse-DFS – Module within Hadoop for mounting HDFS
as a traditional file system
Apache Mahout – Library of machine learning
algorithms for Apache Hadoop
Hue – Browser-based desktop interface for interacting
with Hadoop
Apache Whirr – Library for running Hadoop in the
cloud

DATA PROCESSING
ADVANCED ANALYTICS
1
Two Core Use Cases
Applied Across Verticals
FMV & Image Processing
Data Processing – Full Motion Video & Image Processing
•
Record by record -> Easy Parallelization
–
“Unit of work” is important
–
Raw data in HDFS
•
Adaptation of existing image analyzers to Map Only / Map Reduce
•
Scales horizontally
•
Simple detections
–
Vehicles
–
Structures
–
Faces
Cybersecurity Analysis
Advanced Analytics – Cybersecurity Analysis
•
Rates and flows – ingest can be in excess of the multiple gigabyte per second range
•
Can be complex because of mixed-workload clusters
•
Typically involves ad-hoc analysis
–
Question oriented analytics
•
“Productionized” use cases allow insight by non-analysts
•
Existing open source solution SHERPASURFING
–
Focuses on the cybersecurity analysis underpinnings for common data-sets (pcap, netflow, audit logs, etc.)
–
Provides a means to ask questions without reinventing all the plumbing
Index Preparation
Data Processing – Index Preparation
•
Hadoop’s Seminal Use Case
•
Dynamic Partitioning -> Easy Parallelization
•
String Interning
•
Inverse Index Construction
•
Dimensional data capture
•
Destination indices
•
–
Lucene/Solr (and derivatives)
–
Endeca
Existing solution USA Search (http://usasearch.howto.gov/)
Data Landing Zone
Data Processing – Schema-less Enterprise Data Warehouse / Landing Zone
•
Begins as storage, light ingest processing, retrieval
•
Capacity scales horizontally
•
Schema-less -> holds arbitrary content
•
Schema-less -> allows ad-hoc fusion and analysis
•
Additional analytic workload forces decisions
Hadoop: Getting Started
•
Reactive
–
•
•
Forced by scale or cost of scaling
Proactive
–
Seek talent ahead of need to build
–
Identify data-sets
–
Determine high-value use cases that change organizational outcomes
–
Start with 10-20 nodes and 10+TB unless data-sets are super-dimensional
Either way
–
Talent a major challenge
–
Start with “Data Processing” use cases
–
Physical infrastructure is complex, make the software infrastructure simple to manage
