  • 2. Contents What is Hadoop. Why do we need Hadoop. How Hadoop works. HDFS Architecture. What is Map – Reduce. Hadoop Cluster. Hadoop Processes. Topology of a Hadoop Cluster. Distinction of Hadoop Framework . Prerequisites to learn hadoop.
  • 3. What is Hadoop Hadoop is an open Source Framework. Developed by Apache Software Foundation. Used for distributed processing of large datesets. It works across clusters of computers using asimple programming model (Map-Reduce).
  • 4. Why do we need Hadoop Data is growing faster. Need to process multi petabytes of data. The performance of traditional applicationsis decreasing. The number of machines in a cluster is notconstant. Failure is expected, rather than exceptional.
  • 5. How Hadoop Works The Hadoop core consists of two modules : Hadoop Distributed File System (HDFS)[Storage]. Map Reduce [Processing].MapperReducer
  • 6. HDFS Architecture
  • 7. What is Map – Reduce Map Reduce plays a key role in hadoop framework. Map Reduce is a Programming model for writingapplications that rapidly process large amount ofdata. Mapper – is a function that processes input data togenerate intermediate output data. Reducer – Merges all intermediate data from allmappers and generate final output data.
  • 8. Hadoop Cluster A Hadoop Cluster consist of multiplemachines Which can be classified into 3types Namenode Secondary Namenode Datanode
  • 9. Hadoop Processes Below are the daemons (Processes) Whichruns in a cluster.Name node (Runs on a master machine)Job Tracker (Runs on a master machine)Data node (Runs on slave machines)Task Tracker (Runs on slave machines)
  • 10. Topology of a Hadoop Cluster
  • 11. Distinction Simple – Hadoop allows users to quicklywrite efficient parallel code. Reliable – Because Hadoop runs oncommodity hardware, it can face frequentautomatically handle such failures. Scalable – we can increase or decrease thenumber of nodes (machine) in hadoopcluster.
  • 12. Prerequisites Linux bases operating system (Mac OS, Redhat,ubuntu) Java 1.6 or higher version Disk space ( To hold HDFS data and it’sreplications ) Ram (Recommended 2GB) A cluster of computers. You can even install Hadoop on single machine. For more information visit this link: hadoop onlinetraining
