  • Hortonworks Data Platform (HDP) is the only 100% open source Apache Hadoop distribution that provides a complete and reliable foundation for enterprises that want to build, deploy and manage big data solutions. It allows you to confidently capture, process and share data in any format, at scale on commodity hardware and/or in a cloud environment. \n\nAs the foundation for the next generation enterprise data architecture, HDP delivers all of the necessary components to uncover business insights from the growing streams of data flowing into and throughout your business. HDP is a fully integrated data platform that includes the stable core functions of Apache Hadoop (HDFS and MapReduce), the baseline tools to process big data (Apache Hive, Apache HBase, Apache Pig) as well as a set of advanced capabilities (Apache Ambari, Apache HCatalog and High Availability) that make big data operational and ready for the enterprise.  \n\nRun through the points on left…\n

  • Agile Application Development: Check• LAMP stack mature• Post-Rails frameworks to choose from• Enable rapid feedback and agility + NoSQL © Hortonworks Inc. 2012 10
  • Data Warehousing © Hortonworks Inc. 2012 11
  • Scientific Computing / HPC • ‘Smart kid’ only: MPI, Globus, etc. until HadoopTubes and Mercury (old school) Cores and Spindles (new school) UNIVAC and Deep Blue both fill a warehouse. We’re back... © Hortonworks Inc. 2012 12
  • Data Science? Application Data WarehousingDevelopment 33% 33% 33% Scientific Computing / HPC © Hortonworks Inc. 2012 13
  • Data Center as Computer • Warehouse Scale Computers and applications“A key challenge for architects of WSCs is to smooth out these discrepancies in a cost efficient manner.”Click here for a paper on operating a ‘data center as computer.’ © Hortonworks Inc. 2012 14
  • Hadoop to the Rescue! Big data refinery / Modernize ETL Audio, Web, Mobile, CRM, Video, ERP, SCM, … Images New Data Business Transactions Docs, Sources Text, & Interactions XML HDFS Web Logs, Clicks Big Data Social, Refinery SQL NoSQL NewSQL Graph, Feeds ETL EDW MPP NewSQL Sensors, Devices, RFID Business Spatial, GPS Apache Hadoop Intelligence & Analytics Events, Other Dashboards, Reports, Visualization, … Page 7 © Hortonworks Inc. 2012 15
  • Hadoop to the Rescue!• Easy to use! (Pig, Hive, Cascading)• CHEAP: 1% the cost of SAN/NAS• A department can afford its own Hadoop cluster!• Dump all your data in one place: Hadoop DFS• Silos come CRASHING DOWN!• JOIN like crazy!• ETL like whoah!• An army of mappers and reducers at your command• OMGWTFBBQ ITS SO GREAT! I FEEL AWESOME! © Hortonworks Inc. 2012 16
  • NOW WHAT? © Hortonworks Inc. 2012 ? 17
  • Analytics Apps: It takes a Team• Broad skill-set• Nobody has them all• Inherently collaborative © Hortonworks Inc. 2012 18
  • Data Science Team• 3-4 team members with broad, diverse skill-sets that overlap• Transactional overhead dominates at 5+ people• Expert researchers: lend 25-50% of their time to teams• Creative workers. Run like a studio, not an assembly line• Total freedom... with goals and deliverables.• Work environment matters most © Hortonworks Inc. 2012 19
  • How to get insight into product?• Back-end has gotten t-h-i-c-k-e-r• Generating $$$ insight can take 10-100x app dev• Timeline disjoint: analytics vs agile app-dev/design• How do you ship insights efficiently?• How do you collaborate on research vs developer timeline? © Hortonworks Inc. 2012 20
  • The Wrong Way - Part One“We made a great design. Your job is to predict the future for it.” © Hortonworks Inc. 2012 21
  • The Wrong Way - Part Two“Whats taking you so long to reliably predict the future?” © Hortonworks Inc. 2012 22
  • The Wrong Way - Part Three “The users don’t understand what 86% true means.” © Hortonworks Inc. 2012 23
  • The Wrong Way - Part Four GHJIAEHGIEhjagigehganbanbigaebjnain!!!!!RJ(@J?!! © Hortonworks Inc. 2012 24
  • The Wrong Way - Inevitable Conclusion Plane Mountain © Hortonworks Inc. 2012 25
  • Reminds me of... the waterfall model © Hortonworks Inc. 2012 :( 26
  • Chief ProblemYou can’t design insight in analytics applications. You discover it. You discover by exploring. © Hortonworks Inc. 2012 27
  • -> Strategy So make an app for exploring your data. Iterate and publish intermediate results. Which becomes a palette for what you ship. © Hortonworks Inc. 2012 28
  • Data Design• Not the 1st query that = insight, its the 15th, or the 150th• Capturing “Ah ha!” moments• Slow to do those in batch...• Faster, better context in an interactive web application.• Pre-designed charts wind up terrible. So bad.• Easy to invest man-years in the wrong statistical models• Semantics of presenting predictions are complex, delicate• Opportunity lies at intersection of data & design © Hortonworks Inc. 2012 29
  • How do we get back to Agile? © Hortonworks Inc. 2012 30
  • Statement of Principles (then tricks, with code) © Hortonworks Inc. 2012 31
  • Setup an environment where...• Insights repeatedly produced• Iterative work shared with entire team• Interactive from day 0• Data model is consistent end-to-end• Minimal impedance between layers• Scope and depth of insights grow• Insights form the palette for what you ship• Until the application pays for itself and more © Hortonworks Inc. 2012 32
  • Value document > relationMost data is dirty. Most data is semi-structured or un-structured. Rejoice! © Hortonworks Inc. 2012 33
  • Value document > relationNote: Hive/ArrayQL/NewSQL’s support of documents/array types blur this distinction. © Hortonworks Inc. 2012 34
  • Relational Data = Legacy Format• Why JOIN? Storage is fundamentally cheap!• Duplicate that JOIN data in one big record type!• ETL once to document format on import, NOT every job• Not zero JOINs, but far fewer JOINs• Semi-structured documents preserve data’s actual structure• Column compressed document formats beat JOINs! (paper coming) © Hortonworks Inc. 2012 35
  • Value imperative > declarative• We don’t know what we want to SELECT.• Data is dirty - check each step, clean iteratively.• 85% of data scientist’s time spent munging. See: ETL.• Imperative is optimized for our process.• Process = iterative, snowballing insight• Efficiency matters, self optimize © Hortonworks Inc. 2012 36
  • Value dataflow > SELECT © Hortonworks Inc. 2012 37
  • Ex. dataflow: ETL + email sent count © Hortonworks Inc. 2012 (I can’t read this either. Get a big version here.) 38
  • Value Pig > Hive (for app-dev)• Pigs eat ANYTHING• Pig is optimized for refining data, as opposed to consuming it• Pig is imperative, iterative• Pig is dataflows, and SQLish (but not SQL)• Code modularization/re-use: Pig Macros• ILLUSTRATE speeds dev time (even UDFs)• Easy UDFs in Java, JRuby, Jython, Javascript• Pig Streaming = use any tool, period.• Easily prepare our data as it will appear in our app.• If you prefer Hive, use Hive.But actually, I wish Pig and Hive were one tool. Pig, then Hive, then Pig, then Hive... See: HCatalog for Pig/Hive integration, and this post. © Hortonworks Inc. 2012 39
  • Localhost vs Petabyte scale: same tools• Simplicity essential to scalability: highest level tools we can• Prepare a good sample - tricky with joins, easy with documents• Local mode: pig -l /tmp -x local -v -w• Frequent use of ILLUSTRATE• 1st: Iterate, debug & publish locally• 2nd: Run on cluster, publish to team/customer• Consider skipping Object-Relational-Mapping (ORM)• We do not trust ‘databases,’ only HDFS @ n=3.• Everything we serve in our app is re-creatable via Hadoop. © Hortonworks Inc. 2012 40

  • 2) Create Simple Charts © Hortonworks Inc. 2012 64
  • 2) Create Simple Tables and Charts © Hortonworks Inc. 2012 65
  • 2) Create Simple Charts• Start with an HTML table on general principle.• Then use nvd3.js - reusable charts for d3.js• Aggregate by properties & displaying is first step in entity resolution• Start extracting entities. Ex: people, places, topics, time series• Group documents by entities, rank and count.• Publish top N, time series, etc.• Fill a page with charts.• Add a chart to your event page. © Hortonworks Inc. 2012 66
  • 2.1) Top N (of anything) in Pigpig -l /tmp -x local -v -wtop_things = foreach (group things by key) { sorted = order things by arbitrary_rank desc; top_10_things = limit sorted 10; generate group as key, top_10_things as top_10_things; };store top_n into $mongourl using MongoStorage();Remember, this is the same structure the browser gets as json. This would make a good Pig Macro. © Hortonworks Inc. 2012 67
  • 2.2) Time Series (of anything) in Pigpig -l /tmp -x local -v -w/* Group by our key and date rounded to the month, get a total */things_by_month = foreach (group things by (key, ISOToMonth(datetime)) generate flatten(group) as (key, month), COUNT_STAR(things) as total;/* Sort our totals per key by month to get a time series */things_timeseries = foreach (group things_by_month by key) { timeseries = order things by month; generate group as key, timeseries as timeseries; };store things_timeseries into $mongourl using MongoStorage(); Yet another good Pig Macro. © Hortonworks Inc. 2012 68
  • Data processing in our stackA new feature in our application might begin at any layer... great! omghi2u! I’m creative! I’m creative too! where r my legs? I know Pig! I <3 Javascript! send halp Any team member can add new features, no problemo! © Hortonworks Inc. 2012 69
  • Data processing in our stack... but we shift the data-processing towards batch, as we are able. See real example here. Ex: Overall total emails calculated in each layer © Hortonworks Inc. 2012 70
  • 3) Exploring with Reports © Hortonworks Inc. 2012 71
  • 3) Exploring with Reports © Hortonworks Inc. 2012 72
  • 3.0) From charts to reports...• Extract entities from properties we aggregated by in charts (Step 2)• Each entity gets its own type of web page• Each unique entity gets its own web page• Link to entities as they appear in atomic event documents (Step 1)• Link most related entities together, same and between types.• More visualizations!• Parametize results via forms. © Hortonworks Inc. 2012 73
  • 3.1) Looks like this... © Hortonworks Inc. 2012 74
  • 3.2) Cultivate common keyspaces © Hortonworks Inc. 2012 75
  • 3.3) Get people clicking. Learn.• Explore this web of generated pages, charts and links!• Everyone on the team gets to know your data.• Keep trying out different charts, metrics, entities, links.• See whats interesting.• Figure out what data needs cleaning and clean it.• Start thinking about predictions & recommendations. ‘People’ could be just your team, if data is sensitive. © Hortonworks Inc. 2012 76
  • 4) Predictions and Recommendations © Hortonworks Inc. 2012 77
  • 4.0) Preparation• We’ve already extracted entities, their properties and relationships• Our charts show where our signal is rich• We’ve cleaned our data to make it presentable• The entire team has an intuitive understanding of the data• They got that understanding by exploring the data• We are all on the same page! © Hortonworks Inc. 2012 78
