hadoop vm

Preface: Although it seems that there are not many implementation problems in the process of building a large-scale learning hadoop platform since middle July, for a person who has never been familiar with Linux, Java, and cloud computing platforms before, it took a while. The biggest emotion is that the version of various tools is very important. VMWare, Ubuntu, JDK, hadoop, hbase, Zookeeper, and any ver

Hadoop Core Project: HDFS (Hadoop Distributed File System distributed filesystem), MapReduce (Parallel computing framework)The master-slave structure of the HDFS architecture: The primary node, which has only one namenode, is responsible for receiving user action requests, maintaining the directory structure of the file system, managing the relationship between the file and the block, and the relationship b

Single-machine mode requires minimal system resources, and in this installation mode, Hadoop's Core-site.xml, Mapred-site.xml, and hdfs-site.xml configuration files are empty. By default, the official hadoop-1.2.1.tar.gz file uses the standalone installation mode by default. When the configuration file is empty, Hadoop runs completely locally, does not interact with other nodes, does not use the

There are usually two ways to run Hadoop under Windows: One is to install a Linux operating system with a VM, which basically enables Hadoop to run in a full Linux environment, and the other is to emulate the Linux environment through Cygwin. The advantage of the latter is that it is easy to use and the installation process is simple. Let's take a look at the sec

Hadoop uses Eclipse in Windows 7 to build a Hadoop Development Environment Some of the websites use Eclipse in Linux to develop Hadoop applications. However, most Java programmers are not so familiar with Linux systems. Therefore, they need to develop Hadoop programs in Windows, it summarizes how to use Eclipse in Wind

Although I have installed a Cloudera CDH cluster (see http://www.cnblogs.com/pojishou/p/6267616.html for a tutorial), I ate too much memory and the given component version is not optional. If only to study the technology, and is a single machine, the memory is small, or it is recommended to install Apache native cluster to play, production is naturally cloudera cluster, unless there is a very powerful operation.I have 3 virtual machine nodes this time. Each gave 4G, if the host memory 8G, can ma

The Hadoop 2.2.0 environment is set up based on the online articles. The specific content is as follows. Environment Introduction: I use two laptops, both of which use VMware to install the Fedora 10 system.

Previously introduced me in Ubuntu under the combination of virtual machine Centos6.4 build hadoop2.7.2 cluster, in order to do mapreduce development, to use eclipse, and need the corresponding Hadoop plug-in Hadoop-eclipse-plugin-2.7.2.jar, first of all, before the hadoop1.x in the official Hadoop installation package is self-contained Eclipse plug-in, Now with

Compile the hadoop 2.x Hadoop-eclipse-plugin plug-in windows and use eclipsehadoopI. Introduction Without the Eclipse plug-in tool after Hadoop2.x, we cannot debug the code on Eclipse. We need to package MapReduce of the written java code into a jar and then run it on Linux, therefore, it is inconvenient for us to debug the code. Therefore, we compile an Eclipse plug-in so that we can debug it locally. Afte

Hadoop Streaming provides a toolkit for MapReduce programming that enables Mapper and Reducer based on executable commands, scripting languages, or other programming languages to take advantage of the benefits and capabilities of the Hadoop parallel computing framework, To handle big data.All right, I admit the above is a copy.
