The Linux command line attracts most Linux enthusiasts. A normal Linux user typically has about 50-60 commands to handle daily tasks. Linux commands and their transformations are the most valuable treasures for Linux users, Shell scripting programmers, and administrators.　　Few Linux commands are known, but they are handy and useful, whether you're a novice or an advanced user. Little people know about Linux commands the purpose of this article is to introduce some of the less-known Linux commands that are sure to efficiently ...

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 ...

How to install Nutch and Hadoop to search for Web pages and mailing lists, there seem to be few articles on how to install Nutch using Hadoop (formerly DNFs) Distributed File Systems (HDFS) and MapReduce. The purpose of this tutorial is to explain how to run Nutch on a multi-node Hadoop file system, including the ability to index (crawl) and search for multiple machines, step-by-step. This document does not involve Nutch or Hadoop architecture. It just tells how to get the system ...

ubuntu16.04server install dockerCE. Docker is an application that makes it simple and easy to run applications in containers, just like virtual machines, which are only more portable, more resource-friendly, and more dependent on the host operating system. To learn more about the different components of a Docker container, see Docker Ecosystem: An Introduction to Common Components. There are two ways to install Docker on Ubuntu 16.04. One way is to install it on an existing operating system installation. Another way is to use one ...

Spark can read and write data directly to HDFS and also supports Spark on YARN. Spark runs in the same cluster as MapReduce, shares storage resources and calculations, borrows Hive from the data warehouse Shark implementation, and is almost completely compatible with Hive. Spark's core concepts 1, Resilient Distributed Dataset (RDD) flexible distribution data set RDD is ...

One of the features of cloud computing is the ability to move applications from one processor environment to another. This feature requires a target operating system to receive it before moving the application. Wouldn't it be nice if you could automate the installation of a new operating system? A well-known feature of the intel™ architecture system is the ability to install Linux automatically. However, installing Linux automatically is a tricky issue for System P or IBM power BAE using the hardware management console. This article discusses the solution of ...

In mailbox rapid expansion process, one of the performance problems is the MongoDB database level write lock, the time spent in the lock waiting process, directly reflects the user's use of the service process delay. To address this long-standing problem, we decided to migrate a common set of MongoDB (storing mail-related data) to a separate cluster. According to our inference, this will reduce the lock latency by 50%, and we can add more fragments, and we expect to be able to optimize and manage different types of data independently. We start from Mon ...
