  30. Agenda • What Hadoop gives us • What everyone is complaining about in 2013 • Spark • Berkeley Team • BDAS (Berkeley Data Analytics Stack) • RDDs (Resilient Distributed Datasets) • Shark • Spark Streaming • Other Spark subsystems technicaltidbit.com

  31. What Hadoop Gives Us HDFS Map/Reduce technicaltidbit.com

  32. Hadoop: HDFS Image from mark.chmarny.com technicaltidbit.com

  33. Hadoop: Map/Reduce Image from blog.octo.com Image from people.apache.org/~rdonkin technicaltidbit.com

  34. Map/Reduce Tools Pig Script HiveQL Hbase App Hive Pig Hadoop Linux technicaltidbit.com

  35. Hadoop Distribution Dogs in the Race Hadoop Distribution Query Tool Apache Drill Stinger technicaltidbit.com

  36. Other Open Source Solutions Druid Spark technicaltidbit.com

  37. Not just caching, but streaming 1st generation: HDFS 2nd generation: Caching & “Push” Map/Reduce 3rd generation: Streaming technicaltidbit.com

  38. Berkeley Team Image from Ian Stoica’s slides from Strata 2013 presentation 40 students 8 faculty 3 staff software engineers Silicon Valley style skunkworks office space 2 years into 6 year program technicaltidbit.com

  39. BDAS(Berkeley Data Analytics Stack) Bagel App Shark App Spark Streaming App Bagel Shark Spark Streaming Spark App Spark Hadoop/HDFS Mesos Linux technicaltidbit.com

  40. RDDs(Resilient Distributed Dataset) Image from MateiZaharia’s paper technicaltidbit.com

  41. RDDs: Laziness x => x.startsWith(“ERROR”) lines = spark.textFile(“hdfs://...”) errors = lines.filter(_.startsWith(“ERROR”)) .map(_.split(‘\t’)(2)) .filter(_.contains(“foo”)) cnt = errors.count All Lazy Action! technicaltidbit.com

  42. RDDs: Transformations vs. Actions Transformations map(func) filter(func) flatMap(func) sample(withReplacement, frac, seed) union(otherDataset) groupByKey[K,V](func) reduceByKey[K,V](func) join[K,V,W](otherDataset) cogroup[K,V,W1,W2](other1, other2) cartesian[U](otherDataset) sortByKey[K,V] Actions reduce(func) collect() count() take(n) first() saveAsTextFile(path) saveAsSequenceFile(path) foreach(func) [K,V] in Scala same as <K,V> templates in C++, Java technicaltidbit.com

  43. Hive vs. Shark Shark HiveQL HiveQL HDFS files + HDFS files RDDs technicaltidbit.com

  44. Shark: Copy from HDFS to RDD CREATE TABLE wiki_small_in_mem TBLPROPERTIES ("shark.cache" = "true") AS SELECT * FROM wiki; CREATE TABLE wiki_cached AS SELECT * FROM wiki; Creates a table that is stored in a cluster’s memory using RDD.cache(). technicaltidbit.com

  45. Shark: Just a Shim Shark Images from ReynoldXin’s presentation technicaltidbit.com

  46. What about “Big Data”? PB TB Shark Effectiveness GB MB KB technicaltidbit.com

  47. Median Hadoop job input size Image from Reynold Xin’s presentation technicaltidbit.com

  48. Spark Streaming: Motivation HDFS x1,000,000 clients technicaltidbit.com

  49. Spark Streaming: DStream DStream RDD {{“id”: “hercman”}, “eventType”: “buyGoods”}} {{“id”: “hercman”}, “eventType”: “buyGoods”}} {{“id”: “shewolf”}, “eventType”: “error”}} 2 sec RDD {{“id”: “shewolf”}, “eventType”: “error”}} 2 sec . . . RDD {{“id”: “catlover”}, “eventType”: “buyGoods”}} {{“id”: “hercman”}, “eventType”: “logOff”}} 2 sec “A series of small batches” technicaltidbit.com
