Hadoop
This document discusses Hadoop, an open-source software framework for distributed storage and processing of large datasets across clusters of computers. It describes how Hadoop uses HDFS for scalable, fault-tolerant storage and MapReduce for parallel processing. The core components of Hadoop - HDFS and MapReduce - allow for distributed processing of large datasets across commodity hardware, providing capabilities for scalability, cost-effectiveness, and efficient distributed computing.
HDFS presented by VIJAY
This document provides an overview of Hadoop Distributed File System (HDFS). It discusses what Hadoop is, its main components including HDFS and MapReduce. It describes the architecture and working of HDFS, including how writes and reads occur. It discusses the goals of HDFS in providing a scalable file system and compares it to other systems.
Maintainable cloud architecture_of_hadoop
Kai Sasaki discusses Treasure Data's architecture for maintaining Hadoop on the cloud. Some key points are using stateless services like Hive metastore and cloud storage. They also manage multiple Hadoop versions by downloading packages from S3. Regression tests on Hive queries and a REST API help ensure changes don't cause issues. An RDBMS-based queue provides persistence and scheduling across tasks. The overall aim is high maintainability through statelessness, mobility of components, and queueing of jobs.
How Hadoop Exploits Data Locality
Hadoop exploits data locality by attempting to schedule map tasks on nodes where the input data is already stored locally on disk. This avoids the costly operation of transferring large amounts of data across the network. When slave nodes request new map tasks, the master node prioritizes tasks whose data is local to that slave. If no such local tasks are available, Hadoop tries to schedule tasks where data is on the same rack to achieve rack-level locality. By keeping computation and data close together, Hadoop is able to process large datasets very efficiently in distributed environments.
Asbury Hadoop Overview
This document provides an overview and introduction to Hadoop, HDFS, and MapReduce. It covers the basic concepts of HDFS, including how files are stored in blocks across data nodes, and the role of the name node and data nodes. It also explains the MapReduce programming model, including the mapper, reducer, and how jobs are split into parallel tasks. The document discusses using Hadoop from the command line and writing MapReduce jobs in Java. It also mentions some other projects in the Hadoop ecosystem like Pig, Hive, HBase and Zookeeper.
Hadoop for sys_admin
The document discusses Hadoop for system administrators, covering topics such as why Hadoop is used, how Hadoop works, its architecture, operations, monitoring, high availability, security, backup and recovery, and major Hadoop vendors and distributions. Key components discussed include HDFS, YARN, MapReduce, Spark, and Oozie. Hadoop is used to sort through large amounts of data using distributed processing and storage across commodity hardware. System administration of Hadoop involves planning hardware, operating core services, scheduling and monitoring jobs, and ensuring high availability, security, and disaster recovery. Major Hadoop vendors include Cloudera, Hortonworks, and MapR.
Foss evolution cos-boudnik
This document discusses the evolution of open source software (FOSS) for data, specifically focusing on the Hadoop ecosystem. It notes that FOSS has evolved through an iterative and collaborative process, driven by user demands for simplicity, data preservation, consistency, and high availability. It describes how the Hadoop ecosystem has rapidly advanced through many releases and over 18 components to meet these demands. However, challenges remain around operational complexity and achieving strong consistency and high availability. The document proposes consensus-based replication as an alternative to provide preventative fault tolerance rather than reactive solutions. It introduces WANdisco as a company that provides patented active-active replication technology to solve availability problems for enterprises.

Backup and Disaster Recovery in Hadoop
From: DataWorks Summit Munich 2017 - 20170406
While you could be tempted assuming data is already safe in a single Hadoop cluster, in practice you have to plan for more. Questions like: "What happens if the entire datacenter fails?, or "How do I recover into a consistent state of data, so that applications can continue to run?" are not a all trivial to answer for Hadoop. Did you know that HDFS snapshots are handling open files not as immutable? Or that HBase snapshots are executed asynchronously across servers and therefore cannot guarantee atomicity for cross region updates (which includes tables)? There is no unified and coherent data backup strategy, nor is there tooling available for many of the included components to build such a strategy. The Hadoop distributions largely avoid this topic as most customers are still in the "single use-case" or PoC phase, where data governance as far as backup and disaster recovery (BDR) is concerned are not (yet) important. This talk first is introducing you to the overarching issue and difficulties of backup and data safety, looking at each of the many components in Hadoop, including HDFS, HBase, YARN, Oozie, the management components and so on, to finally show you a viable approach using built-in tools. You will also learn not to take this topic lightheartedly and what is needed to implement and guarantee a continuous operation of Hadoop cluster based solutions.

Cyber-infrastructure Presentation 2015
The document discusses using cyberinfrastructure such as smart traffic lights and smart parking to help reduce traffic in major Saudi Arabian cities. Smart traffic lights would analyze traffic flow and adjust light times accordingly. Smart parking would use cameras to identify available spots and share that data. The conclusion is that if cities implement this strong cyberinfrastructure, it could help make them more organized and beautiful while decreasing traffic and accidents.
DATA BLENDING
The document discusses the rise of data analysts and their use of data blending. It describes how data analysts are taking on more responsibilities and need tools to efficiently analyze large, complex data from multiple sources. Data blending tools allow analysts to easily access both traditional and emerging data, cleanse and prepare it, then perform advanced analytics without relying on IT. This empowers analysts to get answers more quickly and help business decision makers. The key is combining data from different sources into a unified dataset for analysis rather than permanent integration.
Relationship between cloud computing and big data
Cloud computing provides on-demand access to computing resources and applications via the internet. It allows large data to be processed more easily by providing scalable storage and computing power. Storing and analyzing big data in the cloud has benefits like easy use, low costs, and reducing hardware requirements compared to traditional systems. Common cloud platforms that support big data include Amazon Web Services (AWS) and Microsoft Azure, which provide servers, databases, and developer tools via the internet.
Jan 2012 HUG: HCatalog
HCatalog is a table abstraction and a storage abstraction system that makes it easy for multiple tools to interact with the same underlying data. A common buzzword in the NoSQL world today is that of polyglot persistence. Basically, what that comes down to is that you pick the right tool for the job. In the hadoop ecosystem, you have many tools that might be used for data processing - you might use pig or hive, or your own custom mapreduce program, or that shiny new GUI-based tool that's just come out. And which one to use might depend on the user, or on the type of query you're interested in, or the type of job we want to run. From another perspective, you might want to store your data in columnar storage for efficient storage and retrieval for particular query types, or in text so that users can write data producers in scripting languages like perl or python, or you may want to hook up that hbase table as a data source. As a end-user, I want to use whatever data processing tool is available to me. As a data designer, I want to optimize how data is stored. As a cluster manager / data architect, I want the ability to share pieces of information across the board, and move data back and forth fluidly. HCatalog's hopes and promises are the realization of all of the above.

8 принципов создания лендинга, которые обеспечат супер конверсию
В исследовании MarketingSherpa участвовали 2912 сайтов электронной коммерции. Из них почти 38% сообщили, что их процент конверсии лежит в диапазоне от 1% до 5%. Это означает, что более 60% сайтов на самом деле имеют показатель конверсии выше, чем 5%. И это были даже не лендинги!
А ведь лендинг значительно отличается по силе своего воздействия от обычного коммерческого сайта. Промо-страницы созданы специально для достижения конкретной цели. Цель эта, как правило, — конверсия в покупку, и каждый элемент одностраничника направлен на максимизацию этого действия.
