For this reason, future Maven versions might no longer support building such malformed projects. It is highly recommended to fix these problems because they threaten the stability of your build. Some problems were encountered while building the effective model for com.journaldev:java-word-count:jar:1.0-SNAPSHOT When we run this command, it will show us the following Dependency Tree: shubham:JD-Spark-WordCount shubham$ mvn dependency:tree Here is a command which we can use: mvn dependency:tree Finally, to understand all the JARs which are added to the project when we added this dependency, we can run a simple Maven command which allows us to see a complete Dependency Tree for a project when we add some dependencies to it. When we run this project, a runtime instance of Apache Spark will be started and once the program has done executing, it will be shutdown. Here is the pom.xml file with the appropriate dependencies: Ĭom.Īs this is a maven-based project, there is actually no need to install and setup Apache Spark on your machine. Next step is to add appropriate Maven Dependencies to the project. Once you have created the project, feel free to open it in your favourite IDE. If you are running maven for the first time, it will take a few seconds to accomplish the generate command because maven has to download all the required plugins and artifacts in order to make the generation task. To create the project, execute the following command in a directory that you will use as workspace: mvn archetype:generate -DgroupId= -DartifactId=JD-Spark-WordCount -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false We will be using Maven to create a sample project for the demonstration. This was later modified and upgraded so that it can work in a cluster based environment with distributed processing. Apache Spark was created on top of a cluster management tool known as Mesos. It was an academic project in UC Berkley and was initially started by Matei Zaharia at UC Berkeley’s AMPLab in 2009. Apache Spark is an open source data processing framework which can perform analytic operations on Big Data in a distributed environment.
