AGENDA

PROS
 Open-source software framework
 Storage and large-scale data processing
 Easy and economic scaling
 Both structured and unstructured data
 Low-cost commodity hardware
 Starts multiple copies of the same task for
the same block of data
What is Hadoop?
51% OF COMPANIES THINKS ABOUT INTEGRATING
HADOOP IN THEIR COMPANY BY 2016
Philip Russom, TDWI Best Practices Report= Integrating Hadoop into Business

CONS
 Management and high-availability
capabilities are just starting to emerge
 Data security is fragmented
 MapReduce is very batch-oriented
 No easy-to-use, full-feature tools for data
integration, data cleansing, governance
and metadata
 Lacking skilled professionals
What is Hadoop?
MANAGE THE DATA AND USE ANALYTICS TO QUICKLY
IDENTIFY PREVIOUSLY UNKNOWN INSIGHTS: ACCESS
THE DIFFERENT TOOLS OF SAS

WHAT ARE COMPANIES DOING WITH HADOOP?
The percentages mentioned here cover the whole world, not only Europe.
What is Hadoop?
What? Percentage
Data warehouse extensions 46 %
Data exploration and discovery 46 %
Data staging for data warehousing and data integration 39 %
Data lake 39 %
Queryable archive for non-traditional data 36 %
Computational platform and sandbox for advanced analytics 33 %

WHY IS HADOOP (NOT) IMPORTANT?
“Cost savings. Linear scalability. Evaluate ‘the hype’ practically. Complement BI.”
BI architect, telecom, Europe
“Reduces cost of data. New ability to query big data sets. Supply chain improvements. Predictive
analytics.”
Vice president, food and beverage, Asia
“Our existing infrastructure cannot handle the tenfold increase in data volumes.”
Data strategy manager, hospitality, US
“It’s important to realize the potential of big data and to explore new business opportunities.”
Data specialist, consulting, Asia

INTRODUCTION
Project summary
1. Discover web traffic data
• Discover web traffic data
• Sheer volume of data makes it impossible to analyse at the moment
• Prove the added value of a combined Hadoop – SAS environment
2. Lead generation
• More business oriented: scoring a neural network model takes one hour on daily basis
• Reducing this time

Hadoop
 Query test on one day: 35 seconds
 Parsing data on one day: 15 minutes
 Parsing of one week: 53 minutes

Teamwork is key
• Set-up Hadoop cluster with
Hadoop-experts
• Install SAS with experts from
the company
SAS ON HADOOP
 In SAS, take your time to set the correct
variable length
 Choose the strength of the cluster
rationally
 Create Benchmarks on both environments
(server VS Hadoop) early on so a good
comparison can be done and the correct
decision can be taken
 Data must be large enough on Hadoop to
see a difference
