Hadoop Essays

Hadoop has evolved greatly since early 2008, where the Apache Software Foundation initially recognized its importance and promoted it to a top-level open source project. The ‘big data deluge’ is compounding, with IT teams taking a “grab the data first, and figure out what to do with it later” approach. There is no way to predict big data applications in the future. The choice of infrastructure around an organization’s big data is an important one to make. With its constant evolution, IT teams are

Hadoop MapReduce is a framework for processing large data sets in parallel across Hadoop cluster. It uses two steps Map and Reduce process. An initiated job has a map and reduces phases. The map phase counts the words in each document, then reduce phase aggregates the per document data into word counts spanning the entire collection. The reduce phase use the results from map tasks as input to a set of parallel reduce tasks and it consolidate the data into final result. The Map-Reduce uses the key

Hadoop [8] is an open source implementation of MapReduce programming model which runs in a distributed environment. Hadoop consists of two core components namely Hadoop Distributed File System (HDFS) and the MapReduce programming with the job management framework. HDFS and MapReduce both follow the master-slave architecture. A Hadoop program (client) submits a job to the MapReduce framework through the jobtracker which is running on the master node. The jobtracker assigns the tasks to the tasktrackers

De-Identified Personal Health Care System Using Hadoop Dasari Madhavi1, Dr.B.V.Ramana2 1 M.Tech, Department of Information Technology, AITAM, Tekkali, A.P. dasarimadhavi.it@gmail.com 2 Professor & Head of the Department, Information Technology, AITAM, Tekkali, A.P. ramana.bendi@gmail.com ABSTRACT Hadoop technology plays a vital role in improving the quality of healthcare by delivering right information to right people at right time and reduces its cost and time.

social media data requires information gathered to be perfectly structured. This where Facebook came in to rescue and introduced social media industry to a tool called Hadoop. You must be surprised to know that Facebook witnesses nearly 2.5 billion content sharing, 2.7 billion likes and 300 million photo uploads regularly. It uses Hadoop to structure and manage this information and terabytes data it gets converted

of humans a priority. Healthcare industry consists of humungous amount of data. A methodical procedure for analyzing, storing, processing and validating this data is necessary. Therefore to achieve this goal, major techniques like data mining and hadoop have contributed various forms to deliver applications in the area of healthcare. WEKA is a collection of machine learning algorithms that can be used for data mining tasks in healthcare. However, analyzing healthcare data using

nodes in a Hadoop cluster and together connects the file systems on many input and output data nodes to make them into one big file system. The present Hadoop ecosystem, as shown in Figure 1, consists of the Hadoop kernel, MapReduce, the Hadoop distributed file system (HDFS) and a number of related components such as Apache Hive, Hbase, Oozie, Pig and Zoo keeper and these components are explained as below

One of the primary offerings of big data services is that the service is run on a Hadoop platform. A Hadoop platform is unique in that it allows the user to store files across multiple servers, which allow for significantly larger data sets to be utilized. Furthermore, it uses MapReduce, which provides a framework for analyzing many different types

The Travelling Salesman Problem (TSP) is well known in the field of combinatorial optimization. It is a NP-complete problem and there is no efficient method to solve this problem and give best result. Many algorithms are used to solve travelling salesman problem. Some algorithms give optimal solution but some other algorithms gives nearest optimal solution. The genetic algorithm is a heuristic method which is used to improve the solution space for genetic algorithm. The genetic algorithm results

Sears and Roebuck was once the biggest retailer in the history of the United States. Sears has grown from humble beginnings as a catalog and was a leader in home appliances, apparel, lawn and garden, electronics, and the list goes on. Despite their great efforts to strive to become the largest retailers, Sears faced several important issues. When analyzing Sears using the competitive forces and value chain models; Sear could have re-arranged the store sales floor to promote and participate in a venture

The health care industry can and will benefit greatly from big data. As health care professionals look for ways to reduce disease, treat patients, and lower costs, big data will be heavily used to bridge the gaps. Doctors all around the world will be able to enter endless amounts of data and in return, big data can provide valuable statistical information on specific ailments and what factors contributed to development. Once you factor that in with a specific patient, a doctor will be able to make

Next in Comcast's relative ranking of the pillars of being an analytical competitor is measuring the executive support of analytics. At present, there is no shortage of this within Comcast and will only grow as time goes on. A growing mantra of leadership at the company is to support your decisions with data and to only sell new ideas if they have the data to back them up. Often this translates to business intelligence teams working directly with senior management to prove or disprove hypothesis

analytics like, Prof. Tapabrata Maiti, Prof. Vallabh Sambamurthy and Prof. Cheri Speier-Pero, which would provide an edge in the field of analytics. Furthermore, the programme will equip the student with tools like SQL, SAP, Cognos Insight, Weka, Hadoop, Mahout and software tools like R, SAS, SPSS also query languages like SQL/NoSQL, Pig and Hive; which I believe are vital for building a strong base for the successful career in the field of analytics. Therefore, I wish to say, sincerely, that in

ADVANTAGES One of the advantages of allowing employees to use their smartphones for work is by keeping them organized. For instance, smartphone can be used as an automatic reminder and personal organizer. Other than that, flexibility is another advantage of using smartphone during working hours. The employees can use their smartphones to jot down notes or review and edit appointment dates. They can easily do their work anywhere at anytime. The third advantage of allowing employees to use their
