Today, technology with deep learning and machine learning is one of the trends in the tech world, and companies want to hire some programmers with a good background in machine learning. This article will introduce some of the most popular and powerful Java-based machine learning libraries, and I hope to help you.
Knowing how the MapReduce program works, the next step is to implement it through code. We need three things: a map function, a reduce function, and some code to run the job. The map function is represented by the Mapper interface implementation, which declares a map () method. Example 2-3 shows our map function implementation. Example 2-3. Find the highest temperature of the mapper import java.io.IOException; &http ...
Due to the requirements of the project, it is necessary to submit yarn MapReduce computing tasks through Java programs. Unlike the general task of submitting MapReduce through jar packages, a small change is required to submit mapreduce tasks through the program, as detailed in the following code. The following is MapReduce main program, there are a few points to mention: 1, in the program, I read the file into the format set to Wholefileinputformat, that is, not to the file segmentation. 2, in order to control the treatment of reduce ...
This article is my second time reading Hadoop 0.20.2 notes, encountered many problems in the reading process, and ultimately through a variety of ways to solve most of the. Hadoop the whole system is well designed, the source code is worth learning distributed students read, will be all notes one by one post, hope to facilitate reading Hadoop source code, less detours. 1 serialization core Technology The objectwritable in 0.20.2 version Hadoop supports the following types of data format serialization: Data type examples say ...
Foreword in an article: "Using Hadoop for distributed parallel programming the first part of the basic concept 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 based on A parallel program for Hadoop. In this article, we will describe how to write parallel programs based on Hadoop and how to use the Hadoop ecli developed by IBM for a specific computing task.
program example and Analysis Hadoop is an open source distributed parallel programming framework that realizes the MapReduce computing model, with the help of Hadoop, programmers can easily write a distributed parallel program, run it on a computer cluster, and complete the computation of massive data. In this article, we detail how to write a program based on Hadoop for a specific parallel computing task, and how to compile and run the Hadoop program in the ECLIPSE environment using IBM MapReduce Tools. Preface ...
