Foreword in the first article of this series: using Hadoop for distributed parallel programming, part 1th: Basic concepts and installation deployment, introduced the MapReduce computing model, Distributed File System HDFS, distributed parallel Computing and other basic principles, and detailed how to install Hadoop, How to run a parallel program based on Hadoop in a stand-alone and pseudo distributed environment (with multiple process simulations on a single machine). In the second article of this series: using Hadoop for distributed parallel programming, ...

Earlier, we were already running Hadoop on a single machine, but we know that Hadoop supports distributed, and its advantage is that it is distributed, so let's take a look at the environment. Here we use a strategy to simulate the environment. We use three Ubuntu machines, one for the master and the other two for the slaver. At the same time, this host, we use the first chapter to build a good environment. We use the steps similar to the first chapter to operate: 1, the operating environment to take ...

This article is mainly about installing and using hadoop-0.12.0 as an example, pointing out the problems that are easy to meet when you deploy Hadoop and how to solve it. There are 3 machines in the hardware environment, the FC5 system is used, Java is jdk1.6.0.
