Preparing Big Data for Analysis
is an Everyday Challenge

• Very technical skills required
• Divide between M-R developers & analysts
• Beyond the reach of many organizations

Accessible by any ETL
developer, business analyst or data
scientist

Executes inside Hadoop as a native
Java MapReduce task

Use Case Scenario – Call Volume Analysis

• VOIP service provider has excess capacity and is
considering expansion to consumer markets
• Business Analyst: what are the top 10 states for
inbound calls on Fridays, Saturdays and Sundays?
• Research data available:
– Call records – date/timestamp & destination phone #
?
– NANP (North American Numbering Plan) data – area
code by country, state & time zone

7

Solution Requirements

• Data Preparation
– Access the call records in HDFS
– Extract the destination area code for each call
– Read the area code reference data
– Lookup country, state and time zone by area code, append to each
record
– Filter out records (non-U.S. calls, calls made on M-Tu-W-Th)
– Load to a relational database
– Generate metadata
• Analysis
– Explore data multi-dimensionally
– Find the top-10 states by inbound call volume
– Navigate via a geospatial interface
• Deployment
– Deploy in MapReduce to handle larger data volumes

8

Solution Workflow

• Phase I - Business Analysts
– Use a data extract to prepare and validate their analyses
– Iterate over requirements with executives and stake-holders

• Phase II - MapReduce Developers/Analysts
– Create production Pentaho MapReduce transformations
– Manage the deployment and orchestration between the
Hadoop cluster and the production database

9

Data Preparation (Phase I)

• The data pipeline implements the data preparation logic
• Each component has a “personality”– access, calculate, join, filter …
• Free-form design
– As many or as few inputs, transformations and outputs as needed
• Schema contract exists only between connected components
• Pipelined, multi-threaded for performance
• 100% Java-based for deployment flexibility

15

Visualization – Multi-Dimensional UX

16

Visualization – Geographic

17

Visualization - Heatmap

18

Deployment to Hadoop (Phase II)

• To process a larger set of data we can deploy the data pipeline via
MapReduce
– Input and output streams are encoded in key-value pairs
– Two specialized components provide an interface:

– A special job component deploys the data pipeline to the Hadoop
cluster:

SUMMARY

1. The Big Data Fabric encompasses a large collection of Hadoop
distributions, NoSQL and analytical databases
2. A component-based approach to data access and integration can:
– Allow business analysts and data scientists to perform their own data
preparation
– Result in more rapid validation of business requirements & metrics
– Be used to create data pipelines that can be deployed directly to a
cluster, enabling analytics against much larger data sets
– Support orchestration across environments
