Kafka Cluster build Step 1.
Machine preparation In this article, we will prepare three machines to build Kafka cluster, IP address is 192.168.1.1,192.168.1.2,192.168.1.3, and three machines network interoperability. 2. Download and install kafka_2.10-0.8.2.1 download address: https://kafka.apache.org/downloads.html download completed, upload to the target machine, such as 192.168.1.1, use the following com

Some recent projects need to be managed by MAVEN, one of which is to add the previous Eclipse Java Project Project and Web project to MAVEN management, and another scenario is to pull the MAVEN project on SVN locally, Some of the tricky issues encountered in using eclipse, the problem process, and the solution are as follows:1. When you start eclipse after instal
1. File System Description
File systems are generally divided into two types: system and user. System-level file systems: ext3, ext4, DFS, NTFS, etc ,, I will not introduce the complicated distributed or system-level file system,
The architecture design of the Kafka file system is deeply analyzed from the perspective of the high performance of the Kafka architecture.

Kafka is developed in the Scala language and runs on the JVM, so you'll need to install the JDK before installing Kafka.
1. JDK installation configuration 1) do not have spaces in the Windows installation JDK directory name. Set Java_home and CLASSPATH example: Java_home c:\Java\jkd1.8 CLASSPATH.; %java_home%\lib\dt.jar;%java_home%\lib\tools.jar Verification: java-version 2) Linux installatio

There are a number of issues that can be encountered when using distributed databases and distributed computing clusters:
Need to analyze user behavior (pageviews);
The user's search keywords are counted to analyze the current trends
Some data, storage database waste, direct storage drive efficiency and low
These scenarios have one thing in common:
Data is generated by the upstream module, upstream module, using the up

I. Overview of KafkaKafka is a high-throughput distributed publish-subscribe messaging system that handles all the action flow data in a consumer-scale website. This kind of action (web browsing, search and other user actions) is a key factor in many social functions on modern networks. This data is usually resolved by processing logs and log aggregations due to throughput requirements. This is a viable solution for the same log data and offline analysis system as Hadoop, but requires real-time
KAFKA specifies the total amount of data received by topic per minute to monitorRequirements: Get the total amount of data received by Kafka per minute, and save it in a timestamp-topicname-flow format in MySQLDesign ideas:1. Get sum (logsize) at the current point of Kafka and deposit to the specified file file.2. Execute the script again in a minute, get an inst
1:direct Mode Features:1) The direct approach is to directly manipulate the Kafka underlying metadata information so that if the calculation fails, you can reread the data and re-process it. That data is bound to be processed. Pull data, which is the RDD to pull data directly when executing.2) as the direct operation of the Kafka,kafka is the equivalent of your u
