Hadoop Tutorials Cassandra Hector API Request Tutorial About
Home Big Data Hadoop Tutorials Cassandra Hector API Request Tutorial About LABELS: HADOOP-TUTORIAL, HDFS 3 OCTOBER 2013 Hadoop Tutorial: Part 1 - What is Hadoop ? (an Overview) Hadoop is an open source software framework that supports data intensive distributed applications which is licensed under Apache v2 license. At-least this is what you are going to find as the first line of definition on Hadoop in Wikipedia. So what is data intensive distributed applications? Well data intensive is nothing but BigData (data that has outgrown in size) anddistributed applications are the applications that works on network by communicating and coordinating with each other by passing messages. (say using a RPC interprocess communication or through Message-Queue) Hence Hadoop works on a distributed environment and is build to store, handle and process large amount of data set (in petabytes, exabyte and more). Now here since i am saying that hadoop stores petabytes of data, this doesn't mean that Hadoop is a database. Again remember its a framework that handles large amount of data for processing. You will get to know the difference between Hadoop and Databases (or NoSQL Databases, well that's what we call BigData's databases) as you go down the line in the coming tutorials. Hadoop was derived from the research paper published by Google on Google File System(GFS) and Google's MapReduce. So there are two integral parts of Hadoop: Hadoop Distributed File System(HDFS) and Hadoop MapReduce. Hadoop Distributed File System (HDFS) HDFS is a filesystem designed for storing very large files with streaming data accesspatterns, running on clusters of commodity hardware. -
Apache Flink™: Stream and Batch Processing in a Single Engine
Apache Flink™: Stream and Batch Processing in a Single Engine Paris Carboney Stephan Ewenz Seif Haridiy Asterios Katsifodimos* Volker Markl* Kostas Tzoumasz yKTH & SICS Sweden zdata Artisans *TU Berlin & DFKI parisc,[email protected] fi[email protected] fi[email protected] Abstract Apache Flink1 is an open-source system for processing streaming and batch data. Flink is built on the philosophy that many classes of data processing applications, including real-time analytics, continu- ous data pipelines, historic data processing (batch), and iterative algorithms (machine learning, graph analysis) can be expressed and executed as pipelined fault-tolerant dataflows. In this paper, we present Flink’s architecture and expand on how a (seemingly diverse) set of use cases can be unified under a single execution model. 1 Introduction Data-stream processing (e.g., as exemplified by complex event processing systems) and static (batch) data pro- cessing (e.g., as exemplified by MPP databases and Hadoop) were traditionally considered as two very different types of applications. They were programmed using different programming models and APIs, and were exe- cuted by different systems (e.g., dedicated streaming systems such as Apache Storm, IBM Infosphere Streams, Microsoft StreamInsight, or Streambase versus relational databases or execution engines for Hadoop, including Apache Spark and Apache Drill). Traditionally, batch data analysis made up for the lion’s share of the use cases, data sizes, and market, while streaming data analysis mostly served specialized applications. It is becoming more and more apparent, however, that a huge number of today’s large-scale data processing use cases handle data that is, in reality, produced continuously over time. -

Gracias a mi tia Gloria por sus consejos e ideas. Gracias a mi hermano José Daniel y mi cuñada Yule por siempre recordarme que con trabajo y dedicación se pueden alcanzar las metas. [UPM] Máster en Ingeniería Web RESUMEN Big Data ha sido el término dado para aglomerar la gran cantidad de datos que no pueden ser procesados por los métodos tradicionales. Entre sus funciones principales se encuentran la captura de datos, almacenamiento, análisis, búsqueda, transferencia, visualización, monitoreo y modificación. Las empresas han visto en Big Data una poderosa herramienta para mejorar sus negocios en una economía mundial basada firmemente en el conocimiento. Los datos son el combustible para las compañías modernas y, por lo tanto, dar sentido a estos datos permite realmente comprender las conexiones invisibles dentro de su origen. En efecto, con mayor información se toman mejores decisiones, permitiendo la creación de estrategias integrales e innovadoras que garanticen resultados exitosos. Dada la creciente relevancia de Big Data en el entorno profesional moderno ha servido como motivación para la realización de este proyecto. Con la utilización de Java como software de desarrollo y Spring como framework web se desea analizar y comprobar qué herramientas ofrecen estas tecnologías para aplicar procesos enfocados en Big Data. -

A Comprehensive Study of Bloated Dependencies in the Maven Ecosystem
Noname manuscript No. (will be inserted by the editor) A Comprehensive Study of Bloated Dependencies in the Maven Ecosystem César Soto-Valero · Nicolas Harrand · Martin Monperrus · Benoit Baudry Received: date / Accepted: date Abstract Build automation tools and package managers have a profound influence on software development. They facilitate the reuse of third-party libraries, support a clear separation between the application’s code and its ex- ternal dependencies, and automate several software development tasks. How- ever, the wide adoption of these tools introduces new challenges related to dependency management. In this paper, we propose an original study of one such challenge: the emergence of bloated dependencies. Bloated dependencies are libraries that the build tool packages with the application’s compiled code but that are actually not necessary to build and run the application. This phenomenon artificially grows the size of the built binary and increases maintenance effort. We propose a tool, called DepClean, to analyze the presence of bloated dependencies in Maven artifacts. We ana- lyze 9; 639 Java artifacts hosted on Maven Central, which include a total of 723; 444 dependency relationships. Our key result is that 75:1% of the analyzed dependency relationships are bloated. In other words, it is feasible to reduce the number of dependencies of Maven artifacts up to 1=4 of its current count. We also perform a qualitative study with 30 notable open-source projects. Our results indicate that developers pay attention to their dependencies and are willing to remove bloated dependencies: 18/21 answered pull requests were accepted and merged by developers, removing 131 dependencies in total. -

An Enterprise Knowledge Network
Fogbeam Labs Cut Through The Information Fog http://www.fogbeam.com An Enterprise Knowledge Network Knowledge exists in many forms inside your organization – ranging from tacit knowledge which exists only in the minds of the users who possess it, to codified knowledge stored in databases and document repositories. Unfortunately while knowledge exists throughout the organization, it is often not easy (if even possible) to locate, use, share, and reuse existing knowledge. This results in a situation often described as “the left hand doesn't know what the right hand is doing” and damages morale as employees spend their days frustrated and complaining that “nobody knows what is going on around here”. The obstacles that hinder access to existing knowledge can be cultural, geographical, social, and/or technological. And while no technological solution can guarantee perfect knowledge-sharing, tools drawn from big data, data mining / machine learning, deep learning, and artificial intelligence techniques can improve an organization's power to generate, capture, use, share and reuse knowledge. Using technologies developed as part of the semantic web initiative, and applying the principles of linked data within the enterprise, the Fogbeam Labs Enterprise Knowledge Network approach can help your firm integrate and aggregate knowledge which is spread across your existing enterprise applications, content repositories and Intranet. An Enterprise Knowledge Network enables your firm's capabilities to: • engage in high levels of knowledge transfer and -
