flume cd

I haven't written a blog for a long time. We have recently studied storm, flume, and Kafka. Today, I will write down the scenarios and conclusions for testing flume failover and load balance; The test environment contains five configuration files, that is, five agents. A main configuration file, that is, the configuration file (flume-sink.properties) for configur

I. Introduction of FlumeFlume is a distributed, reliable, and highly available mass-log aggregation system that enables the customization of various data senders in the system for data collection, while Flume provides the ability to simply process the data and write to various data-receiving parties (customizable).Design goal:(1) ReliabilityWhen a node fails, the log can be transmitted to other nodes without loss.

http://blog.csdn.net/weijonathan/article/details/18301321Always want to contact storm real-time computing this piece of things, recently in the group to see a brother in Shanghai Luobao wrote Flume+kafka+storm real-time log flow system building documents, oneself also followed the whole, before Luobao some of the articles in some to note not mentioned, some of the wrong points later, In this way I will do the amendment, the content should say that mos

Data acquisitionresponsible for collecting data in real time from each node and choosing Cloudera Flume to realize2). Data Accessbecause the speed of data acquisition and the speed of data processing are not necessarily synchronous, a message middleware is added as a buffer, using Apache's Kafka3). Flow-bas

Recently learned the use of the next flume, in line with the company will be independent of the development of the log system, the official website user manual: Http://flume.apache.org/FlumeUserGuide.htmlFlume schema A. ComponentFirst move, the structure of the Internet.As you can see from the diagram, the Flume event is defined as a data stream, a data stream consisting of an agent, which is actually a JVM

Personal opinion: Big data we all know about Hadoop, but not all of it. How do we build a large database project. For offline processing, Hadoop is still more appropriate, but for real-time, relatively strong, the amount of data is large, we can use storm, then storm and what technology collocation, to be able to do a suitable project. We can refer to the following.You can read this article with the following questions:1. What are the characteristics of a good project architecture?2. How does th

From Bin/flume this shell script can see Flume starting from the Org.apache.flume.node.Application class, which is where the main function of Flume is. The main method first resolves the shell command, throwing an exception if the specified configuration file does not exist. According to the command contains "no-reload-conf" parameters, decide which way to load t

This article is a simple example of the flume official document in the practice and description of the official example Http://flume.apache.org/FlumeUserGuide.html#a-simple-example Flume's Netcat source automatically creates a socket Server that can fetch data simply by sending the data to the netcat source of this socket,flume. Examples are as follows: 1, first configure the agent: in Flume's conf dire

This paper will take timestampinterceptor as an example to analyze how interceptors work in Flume.First, consider the implementation structure of the Interceptor.1. Interceptor interface is realizedThe method of the interface is defined as follows: public void Initialize (); Public event intercept (event event); Public list public void close ();/** Builder implementations must have a no-arg constructor * * Public Interface Builder extends configurable { Publ IC Interceptor Build (); }2.
