  1. TOOLS FOR BIG DATA Sandeep Prasad Dipojjwal Ray GROUP 7

  2. Objectives... • Apache Hadoop • Apache hadoop v1.0.3 and v1.0.4 successful installation • Wordcount functionality by hadoop mapreduce • Estimating value of 'Pi' by hadoop mapreduce • MapReduce and HDFS

  3. Apache Hadoop... • High-Availability Distributed object-oriented platform • Open Source • Pseudo-Distributed single-node cluster • A part of Apache Lucene project • Handles petabytes of data

  4. Installation of Hadoop v1.0.3 & 1.0.4... • Release Date v1.0.3 : October 12, 2012 • Release Date v1.0.4 : May 16, 2012 • OS : Ubuntu v12.04 • Prerequisites : Sun Java, hduser • Configuration

  5. Examples... • WordCount example : • $ /bin/hadoop jar hadoop-1.0.3-examples.jar wordcount file01.txt Estimation of 'Pi' • $ /bin/hadoop jar hadoop-1.0.3-examples.jar pi (x) (y) x= Number of maps y= Sample per maps Runtime 2.25 seconds (x=10 ; y=100) Estimated value 3.1480000000000

  6. MapReduce & HDFS... • Divide and conquer algorithm • Map() and Reduce() function derive roots from functional programming • JobTracker and TaskTracker • NameNode and DataNode • Hadoop Distributed File System • Java Framework

  7. References... • http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster • http://lintool.github.io/Cloud9/ • Data intensive text-processing using Mapreduce Book by Jimmy Lin and Chris Dyer • http://hadoop.apache.org/releases.html • http://www.apache.org/dyn/closer.cgi/hadoop/co

  8. THANK YOU

  9. framework written in Java highly fault-tolerant distributed file system JobTracker web UI provides information about general job statistics of the Hadoop cluster, running/completed/failed jobs and a job history log file The task tracker web UI shows you running and non-running tasks
