Ganglia Installation

Ganglia monitoring software is mainly used to monitor the performance of the software, such as: CPU, MEM, hard disk utilization, I/O load, network traffic, etc., through the curve is very easy to see the work of each node, the reasonable adjustment, distribution system resources, improve the overall performance of the system plays an important role. Support browser access, but can not monitor node hardware specifications, ganglia is a distributed monitoring system, there are two Daemon, respectively: Client ganglia monitoring Daemon (Gmond ...

Back-end development work related to big data for more than a year, with the development of the Hadoop community, and constantly trying new things, this article focuses on the next Ambari, the new http://www.aliyun.com/zixun/aggregation/ 　　14417.html ">apache project, designed to facilitate rapid configuration and deployment of Hadoop ecosystem-related components of the environment, and provide maintenance and monitoring capabilities. As a novice, I ...

Preface Having been in contact with Hadoop for two years, I encountered a lot of problems during that time, including both classic NameNode and JobTracker memory overflow problems, as well as HDFS small file storage issues, both task scheduling and MapReduce performance issues. Some problems are Hadoop's own shortcomings (short board), while others are not used properly. In the process of solving the problem, sometimes need to turn the source code, and sometimes to colleagues, friends, encounter ...

Several articles in the series cover the deployment of Hadoop, distributed storage and computing systems, and Hadoop clusters, the Zookeeper cluster, and HBase distributed deployments. When the number of Hadoop clusters reaches 1000+, the cluster's own information will increase dramatically. Apache developed an open source data collection and analysis system, Chhuwa, to process Hadoop cluster data. Chukwa has several very attractive features: it has a clear architecture and is easy to deploy; it has a wide range of data types to be collected and is scalable; and ...

Currently, the Hadoop distribution has an open source version of Apache and a Hortonworks distribution (HDP Hadoop), MapR Hadoop, and so on. All of these distributions are based on Apache Hadoop.

Design and implementation of recommendation system based on Hadoop Tangjin The main work contents are as follows: 1. Based on the research of the running mechanism of Hadoop and the principle of MapReduce programming, combined with recommendation system and recommendation algorithm, especially the network recommendation algorithm represented by the material diffusion recommendation algorithm and the heat conduction recommendation algorithm, the paper designs and realizes the MapReduce programming scheme of network recommendation algorithm, The complex computing task of this algorithm is decomposed into a series of mapreduce operation Flow, ...
