Hadoop = BigData?

• HUGE Hype factor in 2011 / 2012

Apache Hadoop is a software framework that supports data-intensive distributed applications under a free license• enables applications to work with thousands of nodes and petabytes of data• was inspired by Google's MapReduce and Google File System (GFS) papers

Oracle Loader for Hadoop

SQL Server Connector for Hadoop

Flavors of NoSQL

Column Database

Wide, sparse column sets

RDBMS vs. HadoopTraditional RDBMS Hadoop

Data Size Gigabytes (Terabytes) Petabytes (Hexabytes)

Access Interactive and Batch Batch – NOT Interactive

Updates Read / Write many times Write once, Read many times

Structure Static Schema Dynamic Schema

Integrity High (ACID) Low

Scaling Nonlinear Linear

Query Response Time

Can be near immediate Has latency (due to batch processing)

What about the cloud?

The reality…two pivots

Storage Methods• SQL (RDBMS) • Hadoop

Storage Locations• On premises • Cloud-hosted

Demo - Setting up Your Cluster

Cluster Allocation Process

Working with Hadoop on AzureTools / Languages• MapReduce

• Map (query/format)• Reduce (aggregate)• plug-in for Eclipse (Java)• JavaScript• C# Streaming

• Pig (ETL -- Java)• Hive (HQL Query)

• HBase tables• Others

• Mahout (analyze)• R (analyze)

LinkedIn runs on Hadoop & Voldemort

Klout runs Hadoop (on Azure) &HBase (Hive) & SQL Server SSAS BISM cubes

Hadoop To-Do ListBigData = Hadoop• Use Hadoop when business

needs designate• Use other NoSQL if a better fit

Hadoop on the cloud• Quick and cheap• Specialized use cases

• Behavioral data• dev, test , training

environments

Hadoop access technologies• Learn Map/Reduce• Use HIVE via Excel• Pay attention to Impala
