  • 11. Making the most of the talkSlides will be available after the talk– See @Gagravarr for the linkLots of information and projects to coverJust an overview, see project sites for moreTry to take note / remember the projects youthink will matter to youDont try to take notes oneverything – theres too much!
  • 12. Loading and Querying
  • 13. Pig – pig.apache.orgOriginally from Yahoo, entered the Incubatorin 2007, graduated 2008, very widely usedProvides an easy way to query data, which iscompiled into Hadoop M/R (not SQL-like)Typically 1/20thof the lines of code, and 1/15thof the development timeOptimising compiler – often onlyslower, occasionally faster!
  • 14. Pig – pig.apache.orgShell, scripting and embedded JavaLocal mode for developmentBuilt-ins for loading, filtering, joining,processing, sorting and savingUser Defined Functions tooSimilar range of operations as SQL, butquicker and easier to learnAllows non coders to easily query
  • 15. Gora – gora.apache.orgORM Framework for (NoSQL) Column StoresGrew out of the Nutch projectSupports HBase, Cassanda, HypertableK/V: Voldermort, RedisHDFS Flat Files, plus basic SQLData is stored in Avro (more later)Query with Pig, Lucene, Hive, Cascading,Hadoop M/R, or native Store code
  • 16. Gora – gora.apache.orgExample: Web Server LogAvro data bean, JSON{"type": "record","name": "Pageview","namespace": "org.apache.gora.tutorial.log.generated","fields" : [{"name": "url", "type": "string"},{"name": "timestamp", "type": "long"},{"name": "ip", "type": "string"},{"name": "httpMethod", "type": "string"},{"name": "httpStatusCode", "type": "int"},{"name": "responseSize", "type": "int"},{"name": "referrer", "type": "string"},{"name": "userAgent", "type": "string"}]}
  • 17. Gora// ID is a long, Pageview is compiled Avro beandataStore = DataStoreFactory.getDataStore(Long.class, Pageview.class);// Parse the log file, and storewhile(going) {Pageview page = parseLine(reader.readLine());dataStore.put(logFileId, page);}DataStore.close();private Pageview parseLine(String line) throws ParseException {StringTokenizer matcher = new StringTokenizer(line);//parse the log lineString ip = matcher.nextToken();...//construct and return pageview objectPageview pageview = new Pageview();pageview.setIp(new Utf8(ip));pageview.setTimestamp(timestamp);...return pageview;}
  • 18. Accumulo – accumulo.apache.orgDistributed Key/Value store, built on top ofHadoop, Zookeeper and ThriftInspired by BigTable, with someimprovements to the designCell level permissioning (access labels),write constraints, and server side hooks totweak data as its read/writtenSupports v.large rowsInitial work mostly done by the NSA!
  • 19. Accumulo – accumulo.apache.orgHigh availability (uses Zookeeper)Distributed WAL via loggers, later to HDFSLogical time – tablets can have wrong dates!FATE – Fault Tolerant ExecutionsTesting Friendly!Mocks, Functional Tests, Scaling Tests, andrandom walk testsAdmin support OOTB
  • 20. Sqoop – sqoop.apache.org (no u!)Bulk data transfer tool for big data systemsHadoop (HDFS), HBase and Hive on one sideSQL Databases on the otherCan be used to import existing data into yourbig data clusterOr, export the results of a big datajob out to your data wharehouseGenerates code to work with data
  • 21. Chukwa (Incubating)Log collection and analysis framework basedon HadoopIncubating since 2010Collects and aggregates logs from manydifferent machinesStores data in HDFS, in chunks that are bothHDFS and Hadoop friendlyLets you dump, query and analyze
  • 22. Chukwa (Incubating)Chukwa agent runs on source nodesCollects from Log4j, Syslog, plain text logfiles etcAgent sends to a Collector on the HadoopclusterCollector can transform if neededData written to HDFS, and optionallyto HBase (needed for visualiser)
  • 23. Chukwa (Incubating)Map/Reduce and Pig query the HDFS files,and/or the HBase storeCan do M/R anomaly detectionCan integrate with Hiveeg Netflix collect weblogs with Chukwa,transform with Thrift, and store in HDFSready for Hive queries
  • 24. Flume – flume.apache.orgAnother Log collection frameworkConcentrates on rapidly collecting,aggregating and moving large amounts oflogs from many sources to a central placeTypically write to HDFS + Hive + FTSSource, Channels and SinksSource consumes events, eglog file entries, avro data
  • 25. Flume – flume.apache.orgSource places into a 1 or more channels,which can be persistent or in-memorySink pulls events from channel, then storesCan chain together, fan-in or fan-outData and Control planes independentDoes more OOTB than ChukwaAdding source+sink easyLess scope to customise otherwise
  • 26. Flume – flume.apache.orgAnother Log collection frameworkConcentrates on rapidly getting data to avariety of sourcesTypically write to HDFS + Hive + FTSJoint Agent+Collector modelData and Control planes independentMore OOTB, less scope to alter

  • 28. Falcon (Incubating)Data LifeCycle Management for HadoopProvides support to applications to implementthe key parts – import, export, cleaning,duplication, recovery, retention etcDeclarative definitions, Falcon does deps etcControlled replication, for example only outputsof certain stages in the flowLots of tests for the key parts

  • 30. MRQL – mrql.apache.orgMRQL, pronounced as MiracleLarge scale data analytics engineWorks on top of Hadoop or HamaSQL-like query languageSupports more complex types and constructsthan Pig or Hive, so you can avoid having towrite explicit M/R codePage Rank, k-means, matrix etc
  • 31. Tajo (Incubating)Data warehouse system for HadoopLow-latency and scalable ad-hoc queriesHDFS for storage, custom query engine whichcontrols execution, optimisation and data flowRuns SQL queries, inc filter, group, sort, joinSome ETL for data format translationJava API to submit queriesCommand line tools
  • 32. Building MapReduce Jobs
  • 33. Avro – avro.apache.orgLanguage neutral data serializationRich data structures (JSON based)Compact and fast binary data formatCode generation optional for dynamiclanguagesSupports RPCData includes schema details
  • 34. Avro – avro.apache.orgSchema is always present – allows dynamictyping and smaller sizesJava, C, C++, C#, Python, Perl, Ruby, PHPDifferent languages can transparently talk toeach other, and make RPC calls to eachotherOften faster than Thrift and ProtoBufNo streaming support though
  • 35. Thrift – thrift.apache.orgJava, C++, Python, PHP, Ruby, Erlang, Perl,Haskell, C#, JS, Cocoa, OCaml and more!From Facebook, at Apache since 2008Rich data structure, compiled down intosuitable codeRPC support tooStreaming is availableWorth reading the White Paper!
  • 36. HCatalog (Just joined Hive)Provides a table like structure on top of HDFSfiles, with friendly addressingAllows Pig, Hadoop MR jobs etc to easilyread/write data structured dataSimpler, lighter weight than Avro or Thriftbased serialisationBased on Hives metastore formatDoesnt require an additional datastore
  • 37. MRUnit – mrunit.apache.orgBuilt on top of JUnitChecks Map, Reduce, then combinedProvides test drivers for HadoopAvoids you needing lots of boiler plate codeto start/stop HadoopAvoids brittle mock objectsHandles multiple input K/VsCounter checking
  • 38. MRUnitIdentityMapper – same input/outputpublic class TestExample extends TestCase {private Mapper mapper;private MapDriver driver;@Beforepublic void setUp() {mapper = new IdentityMapper();driver = new MapDriver(mapper);}@Testpublic void testIdentityMapper() {// Pass in { “foo”, “bar” }, ensure it comes back againdriver.withInput(new Text("foo"), new Text("bar")).withOutput(new Text("foo"), new Text("bar")).runTest();assertEquals(1, driver.getCounters().findCounter(“foo”,”bar”));}}
