Twitter Storm notes

Storm Study Notes

Get ready

1. Learn the most basic ways to use Git, because both the storm case and the source code are managed with Git.

2. Learn how maven is used, because many jar packages are used in the project, which can be cumbersome to manage.

Maven Address: http://maven.apache.org/index.html

Begin

Install locally and download the latest storm. Address: http://storm-project.net/downloads.html

Download the Storm-starter and import it into eclipse

Use git command to clone Storm-starter project to Local: Git clone https://github.com/nathanmarz/storm-starter.git

Modifying the M2-pom.xml file name in the project is called Pom.xml. Maven only recognizes Pom.xml

Go to the project directory and use MAVEN to download the relevant jar

Maven command cleans up the installation jar package to the local repository: mvn clean install

Note the jar that was wall
