I was fortunate enough to take the MOOC college Hadoop experience class at the academy.This is the little Elephant College hadoop2. X's Notes As the usual data mining do more, so the priority to see Mahout direction video.Mahout has good extensibility and fault tolerance (based on hdfsmapreduce development), which realizes most commonly used data mining algorithm

object-oriented, easy to operate. Both Hadoop and data mining require the foundation of a high-level programming language. Therefore, if you want to learn big data development, you need to be proficient in at least one high-level language.According to statistical statistics, the company's demand for Java

platform implementation technologies mainly focus on hadoop and cloud computing systems. They must achieve rapid technological breakthroughs in these fields.In order to speed up the promotion of big data, China Merchants Bank began to look for partners with technical strength. At this time, they formed a cooperative relationship with Huawei, with the help of Hua

NetEase Big Data Platform Spark technology practice author Wang Jian Zong NetEase's real-time computing requirementsFor most big data, real-time is the important attribute that it should have, the arrival and acquisition of information should meet the requirement of real time, and the value of information needs to be m

This article is a combination of mapreduce in Hadoop to analyze user data, statistics of the user's mobile phone number, uplink traffic, downlink traffic, total traffic information, and can be in accordance with the total traffic size of the user group sorting. is a very simple and easy to use Hadoop project, the main users to further enhance the understanding of

HadoopBasically the Hadoop and storm frameworks are used to analyze big data. They complement each other and differ in some ways. Apache Storm performs all operations except persistence, while Hadoop is good in all respects, but lags behind real-time computing. The following table compares the properties of storm and

Many data scientists prefer to use the R language, and it is gratifying that the integration of Spark and R-Sparkr has become the spark's emerging capabilities. Apache Zeppelin (https://zeppelin.incubator.apache.org/) is an emerging tool that provides Spark-based Notebook capabilities, which are available in Apache Zeppelin for Sp The u

At the Talend Connect conference, an IT industry analyst pointed out that companies would likely be eliminated from their peers if they did not grasp the opportunities offered by large data. Jeff Kelly is Wikibon.org's chief researcher and editor of Siliconangle. Big data technologies such as Hadoop and MapReduce are

cause oom, this is a fatal problem, the first can not handle large-scale data, the second spark can not run on a large-scale distributed cluster! Later, the solution was to add the shuffle consolidate mechanism to reduce the number of files produced by shuffle to C*r (c represents the number of mapper that can be used at the cores side, and R represents the number of concurrent tasks in reducer). But at this time if the reducer side of the parallel
