Hadoop World 2011: How Hadoop Revolutionized Business Intelligence and Advanced Data Analytics at Yahoo - Amr Awadallah, Cloudera

"Amr Awadallah served as the VP of Engineering of Yahoo's Product
Intelligence Engineering (PIE) team for a number of years. The PIE
team was responsible for business intelligence and advanced data
analytics across a number of Yahoo's key consumer facing properties (search, mail, news, finance, sports, etc). Amr will share the data architecture that PIE had implementted before Hadoop was deployed and the headaches that architecture entailed. Amr will then show how most, if not all of these headaches were eliminated once Hadoop was deployed. Amr will illustrate how Hadoop and Relational Database complement each other within the traditional business intelligence data stack, and how that enables organizations to access all their data under different
operational and economic constraints."

  • 1. November 2011How Apache Hadoop is RevolutionizingBusiness Intelligence and Data AnalyticsDr. Amr Awadallah | Founder, CTO, VP of, twitter: @awadallah
  • 2. Business Intelligence Before Adopting Apache Hadoop BI Reports + Interactive Apps Can’t Explore Original High Fidelity Raw Data RDBMS (processed data) ETL Compute Grid Moving Data To Compute Doesn’t Scale Storage Only Grid (original raw data) Archiving = Mostly Append Premature Collection Data Death Instrumentation2 ©2011 Cloudera, Inc.

Business Intelligence After Adopting Apache Hadoop Data Exploration & BI Reports + Interactive Apps Advanced Analytics RDBMS ETL and Aggregations Complex Data Processing Hadoop: Storage + Compute Grid Keep Data Alive For Ever Collection Instrumentation3 ©2011 Cloudera, Inc.

  • 4. So What is Apache Hadoop ?• A scalable fault-tolerant distributed system for data storage and processing (open source under the Apache license).• Core Hadoop has two main components: – Hadoop Distributed File System: self-healing high-bandwidth clustered storage. – MapReduce: fault-tolerant distributed processing.• Key business values: – Flexible – Store any data, Run any analysis (Mine First, Govern Later). – Scalable – Start at 1TB/3-nodes then grow to petabytes/1000s of nodes. – Affordable – Cost per TB at a fraction of traditional options. – Open Source – No Lock-In, Rich Ecosystem, Large developer community. – Broadly adopted – A large and active ecosystem, Proven to run at scale. 4 ©2011 Cloudera, Inc.

  • 5. The Main Benefit: Agility/FlexibilitySchema-on-Write (RDBMS): Schema-on-Read (Hadoop):• Schema must be created before • Data is simply copied to the file data is loaded store, no transformation is needed• Explicit load operation has to • A SerDe (Serializer/Deserlizer) is take place which transforms applied during read time to extract data to DB internal structure the required columns• New columns must be added • New data can start flowing anytime explicitly before data for such and will appear retroactively once columns can be loaded into the the SerDe is updated to parse it database• Read is Fast • Load is Fast Benefits• Standards/Governance • Flexibility/Agility 5 ©2011 Cloudera, Inc.

  • 6. What is Complex Data Processing?1. Java MapReduce: Most flexibility and performance, but tedious development cycle (the “assembly language” of Hadoop).2. Streaming MapReduce (also Pipes): Allows you to develop in any programming language of your choice, but slightly lower performance and less flexibility than native Java MapReduce.3. Crunch: A library for multi-stage MapReduce pipelines in Java.4. Pig Latin: A high-level language out of Yahoo, suitable for batch data flow workloads.5. Hive: A SQL interpreter out of Facebook, also includes a meta- store mapping files to their schemas and associated SerDes.6. Oozie: A PDL XML workflow engine that enables creating a workflow of jobs composed of any of the above.6 ©2011 Cloudera, Inc. All Rights Reserved.
