slide 13:

What is Hadoop Hadoop was created by Doug Cutting and Mike Cafarella. Hadoop provides the reliable shared storage and analysis system. It is designed to scale up from a single server to thousand of machines with a high degree of fault tolerance. www.easylearning.guru

slide 14:

Hadoop History www.easylearning.guru

slide 15:

Hadoop Core Components Core Hadoop has two main systems: • Hadoop Distributed File System: The Hadoop file system is a Distributed file system which holds the large amount of data across multiple nodes in a cluster. • MapReduce: MapReduce is a distributed programming paradigm used to analyze the data in the HDFS. www.easylearning.guru

slide 16:

Hadoop Distributed File System HDFS A given file is broken down into blocks default64MB then blocks are replicated across cluster default3. Optimized for throughput. HDFS allows you to put/get/delete files. Follows the philosophy Write Oce ad Read Multiple ties Block Replication for: - Durability High Availability and Throughput. www.easylearning.guru

slide 17:

MapReduce Flow www.easylearning.guru

slide 18:

MapReduce Framework Map Reduce works by breaking the processing into two phases : Map Phase and Reduce Phase. www.easylearning.guru
