1 Hadoop2, Spark Big Data, real time, machine learning & use cases Cédric Carbone Twitter
2 Agenda Map Reduce Hadoop v1 limits Hadoop v2 and YARN Apache Spark Streaming : Spark vs Storm Machine Learning : Recommender System Use Case : Next Product To Buy Q&A
3 What s hadoop The Apache Hadoop project develops opensource software for reliable, scalable, distributed computing. Java framework for storage and running data transformation on large cluster of commodity hardware Licensed under the Apache v2 license Created from Google's MapReduce, BigTable and Google File System (GFS) papers
4 HDFS : Distributed Storage Distributed, Scalable, Portable, Reliable file system for the Hadoop framework. Metadata / data separation: Name Nodes Data Nodes
5 Map Reduce Map() : parse inputs and generate 0 to n <key, value> Reduce() : sums all values of the same key and generate a <key, value> WordCount Example Each map take a line as an input and break into words It emits a key/value pair of the word and 1 Each Reducer sums the counts for each word It emits a key/value pair of the word and sum

14 Hadoop MapReduce v1 Not good for low-latency jobs on smallest dataset
15 Hadoop MapReduce v1 Good for off-line batch jobs on massive data
16 Hadoop 1 Batch ONLY High latency jobs HIVE Query Pig Scripting Cascading Accelerate Dev. MapReduce1 Cluster Resource Management + Data Processing BATCH HDFS (Redundant, Reliable Storage)
17 Hadoop2 : Big Data Operating System Customers want to store ALL DATA in one place and interact with it in MULTIPLE WAYS Simultaneously & with predictable levels of service Data analysts and real-time applications MapReduce1 Data Processing BATCH Other Data Processing YARN (Cluster Resource Management) HDFS (Redundant, Reliable Storage)

21 Apache Spark is a fast and general engine for large-scale data processing.
22 The most active project Patches MapReduce Storm Yarn Spark Lines Added MapReduce Storm Yarn Spark
23 Spark won the Daytona GraySort contest! Sort on disk 100TB of data 3x faster than Hadoop MapReduce using 10x fewer machines. Run programs up to 100x faster than Hadoop MapReduce in memory, or 10x faster on disk.
24 RDD & Operation Resilient Distributed Datasets (RDDs) Operations Transformations (e.g. map, filter, groupby) Actions (e.g. count, collect, save)
