Concepts on Hadoop
Hadoop is an open source software framework that allows for the distributed storage and processing of extremely large datasets across clusters of commodity hardware. It uses a scalable distributed file system called HDFS to store data reliably, and its MapReduce programming model enables parallel processing of huge datasets across large clusters of servers. The Hadoop ecosystem includes additional popular tools like Pig, Hive, HBase, and Zookeeper that provide SQL-like querying, real-time database access, and coordination services to make the Hadoop platform more full-featured and user-friendly.
Big data and hadoop
This document discusses big data and the Apache Hadoop framework. It defines big data as large, complex datasets that are difficult to process using traditional tools. Hadoop is an open-source framework for distributed storage and processing of big data across commodity hardware. It has two main components - the Hadoop Distributed File System (HDFS) for storage, and MapReduce for processing. HDFS stores data across clusters of machines with redundancy, while MapReduce splits tasks across processors and handles shuffling and sorting of data. Hadoop allows cost-effective processing of large, diverse datasets and has become a standard for big data.

Hadoop or Spark: is it an either-or proposition? By Slim Baltagi
Hadoop or Spark: is it an either-or proposition? An exodus away from Hadoop to Spark is picking up steam in the news headlines and talks! Away from marketing fluff and politics, this talk analyzes such news and claims from a technical perspective.
In practical ways, while referring to components and tools from both Hadoop and Spark ecosystems, this talk will show that the relationship between Hadoop and Spark is not of an either-or type but can take different forms such as: evolution, transition, integration, alternation and complementarity.
Brig waseem closed versus open managemnt of condylar fractures
This document discusses treatment options for mandibular condyle fractures, including open reduction and internal fixation (ORIF) versus closed reduction. Closed reduction involves immobilization with devices like eyelet wiring or splints, while open reduction requires surgical access to reposition the condyle. The choice depends on factors like fracture level and displacement. While open reduction maintains posterior facial height and enables early function, closed reduction risks malocclusion and chronic pain. Overall, available evidence indicates that acceptable outcomes can result from either approach depending on the individual patient and case specifics.

surgical approaches to the mandibular condyle
This document discusses surgical approaches for treating mandibular condylar fractures. It describes several transcutaneous approaches like pre-auricular, retromandibular, and submandibular as well as intraoral endoscopic approaches. The preauricular approach involves making incisions above and below the tragus to expose the condylar head and neck. The retromandibular approach requires an incision behind the ramus to dissect through the parotid gland and expose the condylar neck. Selection of the best surgical approach depends on factors like the fracture level, existing lacerations, need for exposure, and risk of complications.
Einde voor NV Hasselt Stationsomgeving
De NV Hasselt Stationsomgeving werd op 10 december 2003 opgericht.
In de laatste akte in het Staatsblad zien we Hilde Claes als voorzitster van de NV.
De NV werd opgericht om de ontwikkelingen rondom de stationsomgeving van Hasselt te coördineren. Door de samenwerkingsovereenkomst tussen het Vlaams Gewest, de NMBS-Holding, de Vlaamse Vervoersmaatschappij, de stad Hasselt en de nv HSO werd die NV aangeduid als projectcoördinator.
De projectpartners hebben in 2016 evenwel beslist de coördinatieopdracht stop te zetten omdat er geen verdere projecten gepland waren.
De stad Hasselt en Eurostation hebben daarom volgens minister Bellot beslist de mogelijkheid tot vereffening te onderzoeken . Alles is volgens hem besproken tussen de partners. ‘Het financiële resultaat, dat momenteel positief is, zal tussen beide partners worden verdeeld.’ Het einde van de NV is dus in zicht.

Hadoop training
Hadoop is one of the booming and innovative data analytics technology which can effectively handle Big Data problems and achieve the data security. It is an open source and trending technology which involves in data collection, data processing and data analytics using HDFS (Hadoop Distributed File System) and MapReduce algorithms.
Hadoop
Hadoop is an open-source framework for distributed storage and processing of large datasets across clusters of commodity hardware. It was created to support applications handling large datasets operating on many servers. Key Hadoop technologies include MapReduce for distributed computing, and HDFS for distributed file storage inspired by Google File System. Other related Apache projects extend Hadoop capabilities, like Pig for data flows, Hive for data warehousing, and HBase for NoSQL-like big data. Hadoop provides an effective solution for companies dealing with petabytes of data through distributed and parallel processing.
Hadoop
This document discusses big data and the Hadoop platform. It provides an overview of Hadoop versions 1 and 2. Hadoop version 1 included the Hadoop Distributed File System (HDFS) for large-scale storage and the MapReduce programming model. Hadoop version 2 introduced YARN to address MapReduce limitations like scalability and availability. The document also briefly describes the Hadoop ecosystem of related projects like Hive for data warehousing and Pig for data flows. It provides examples of Twitter and Facebook's use of Hadoop for big data analytics.
Unit 3 intro.pptx
Hadoop is an open source software framework for storing and processing large datasets across clusters of computers using simple programming models. It provides distributed storage and computation across clusters allowing data to be processed in parallel. Hadoop is designed to scale from a single server to thousands of machines, with each offering local computation and storage resources.

Hadoop is an open-source software framework for distributed storage and processing of large datasets across clusters of computers. It allows for the reliable, scalable, and distributed processing of large data sets across clusters of commodity hardware. The core of Hadoop includes a storage part called HDFS for reliable data storage, and a processing part called MapReduce that processes data in parallel on a large cluster. Hadoop also includes additional projects like Hive, Pig, HBase, Zookeeper, Oozie, and Sqoop that together form a powerful data processing ecosystem.
