Hadoop On Demand Management Guide

Overview Hadoop on Demand (HOD) is a system that can supply and manage independent Hadoop map/reduce and Hadoop Distributed File System (HDFS) instances on a shared cluster. It makes it easy for administrators and users to quickly build and use Hadoop. Hod is also useful for Hadoop developers and testers who can share a physical cluster through hod to test their different versions of Hadoop. Hod relies on resource Manager (RM) to assign nodes ...

10 basic practical algorithms that programmers must know and their explanations

Algorithm one: Fast sorting algorithm is a sort algorithm developed by Donny Holl. In average, sort n items to be 0 (n log n) times compared. In the worst-case scenario, 0 (N2) comparisons are required, but this is not a common situation.   In fact, fast sorting is typically faster than the other 0 (n log n) algorithms because its internal loops (inner Loop) can be implemented efficiently on most architectures. Quick sort using divide-and-conquer method (http://www ...)

Hadoop Cluster Build

Objective This article describes how to install, configure, and manage a meaningful Hadoop cluster, which can scale from small clusters of nodes to thousands of-node large clusters. If you want to install Hadoop on a single machine, you can find the details here. Prerequisites ensure that all required software is installed on each node in your cluster. Get the Hadoop package. Installing the Hadoop cluster typically extracts the installation software onto all the machines in the cluster. Usually, one machine in the cluster is designated as Namenode, and the other is different ...

The composition and application of virtualization technology in deep analysis cloud storage

Storage Domain International Authority SNIa (Storage Network Industry Association) gives the definition of storage virtualization (Storagevirtualization): "By abstracting, hiding, or isolating the internal functions of the storage System/subsystem from applications, compute servers, network resources, Implement storage and data management independent of applications and networks. Storage virtualization technology is to abstract the underlying storage devices unified management, to the server layer to mask the specificity of storage device hardware, but only to retain their unified logic ...
