on the other hand,(ii) a reduce function that merges all intermediate values associated with the same intermediate key 41.6 1 Big data the open source computing framework Hadoop have received a growing interest

and energy (Footnote 4 continued) Mapreduce has been used to rewrite the production indexing system that produces the data structures used for the Google web search service 41.5 See for example how IBM has exploited/integrated Hadoop 42.1.1 Introduction 7 management.

and Hadoop at the core of Nokia's infrastructure. POINT OF ATTENTION: Big data ask for a clear understanding of both IT Portfolio and data asset,

As reported by Cloudera 33 the centralized Hadoop cluster actually contains 0. 5 PB of data.

and efficiently moving of data from, for example, servers in Singapore to a Hadoop cluster in the UK data center.

The solution has been found in Cloudera's Distribution that includes Apache Hadoop (CDH bundling the most popular open source projects 1. 2 Case studies 17 in the Apache Hadoop stack into a single, integrated package.

In 2011, Nokia put its central CDH cluster into production to serve as the company's information core.

analytics for enterprise class hadoop and streaming data, 1st edn. Mcgraw-hill Osborne Media, New york References 21 Chapter 2 Cloud computing Abstract During the last decade, the Information and Communication Technology (ICT) industry has been transformed by innovations that fundamentally changed the way

These applications use the Mapreduce frameworks such as Hadoop for scalable and fault-tolerant data processing. However

modeling the performance of Hadoop tasks (either online or offline) and the adaptive scheduling in dynamic conditions form an important challenge in cloud computing. 8. Storage technologies and data management.

Big data Amazon's Dynamo, HBASE, Google's Bigtable, Cassandra, Hadoop, etc. Ultra-fast, low latency switches Cisco Networks, etc.

Hadoop: A batch-oriented programming framework that supports the processing of large data sets in a distributed computing environment.

Hadoop is written in the Java programming language and is a top-level Apache project (Apache is decentralized a community of developers supporting open-source software).

and portable file system written in Java for the Hadoop framework. Hive: A data warehouse infrastructure built on top of Hadoop,

providing data summarization, query, and analysis. It permits queries over the data using a familiar SQL-like syntax.

and moving large amounts of log data from applications to Hadoop. Mahout: A library of Hadoop implementations of common analytical computations.

Oozie: A workflow scheduler system developed to manage Hadoop jobs. Pig: A platform for analyzing large datasets that consists of a high-level language (Pig Latin) for expressing data analysis programs,

coupled with infrastructure for evaluating these programs. R: R is a free software programming language and software environment for statistical computing and graphics.

A tool facilitating the transfer of data from relational databases into Hadoop. Zookeeper: A centralized service for maintaining configuration information, naming, providing distributed synchronization,

Technologies include Hadoop (which enables largescale processing of diverse datasets), R (a programming language for statistics),

Free open-source technologies such as Hadoop (which enables large-scale processing of diverse datasets) are typically not immediately usable.

and train data scientists and analysts in Hadoop programming, or to buy an enterprise-ready version of Hadoop.

If the outcome of big data analysis is mission-critical for your business, it probably makes sense to use only purpose-built hardware.

and combining data on Hadoop with data from traditional databases to turn its marketing staff from Mad Men to Math Men.
