You can download Maven from its Apache homepage. The Scala Maven Plugin requires Maven 3.0+ Manually (Red Hat Linux, OSX, Windows) If you don’t have it, you can get it with the package managers MacPorts, Homebrew, or Fink. OSX prior to 10.9 (Mavericks) comes with Maven 3 built in.

Just do (sudo) apt-get install maven and you’re good to go. On Debian and Debian-derivatives, Maven is usually available via apt-get. Note: the plugin includes Scala from the Central Repository so there’s no need to install it yourself if you’re compiling with Maven. We’ll be using the Scala Maven Plugin ( GitHub repo, website) (formerly known as the maven-scala-plugin renamed to honour the new naming policy where only Maven core plugins are prefixed with “maven”), by far the dominant plugin for Scala projects. If you’re familiar with Maven, you can go ahead with the Scala Maven Plugin. You can also check out the official example project which uses the same Scala plugin we will show here. These “artifacts” are downloaded from repositories such as The Central Repository. For example, adding a new dependency usually involves only 5 extra lines in the pom.xml. Maven is a plugin-based architecture, making it easy to add new libraries and modules to existing projects. It favours “convention over configuration” it can greatly simplify builds for “standard” projects and a Maven user can usually understand the structure of another Maven project just by looking at its pom.xml (Project Object Model).

This is Eclipse Juno in windows 7 and I have the CHD ready in a Linux machine.ĪrtifactDescriptorException: Failed to read artifact descriptor for :hadoop-hdfs:jar:2.0.0-cdh4.0.0: ArtifactResolutionException: Failure to transfer :hadoop-hdfs:pom:2.0.0-cdh4.0.0 from was cached in the local repository, resolution will not be reattempted until the update interval of cloudera has elapsed or updates are forced. I did everything as u have described, but still Maven is not able to connect to Cloudera repo. I have been trying to get Maven to download the libs for the past 1 week, but this error wont go away. hadoop jar MapReduce-0.0.1-SNAPSHOT.jar .WordCount input outputĮach time I need to create a new Hadoop project, I simply copy pom.xml template described above, and that’s it.
This jar is ready to be executed on your Hadoop environment. You need to explicitly add cloudera repo in your settings.xml (under $/.m2 local repository). Prerequisite maven 3Ĭloudera jar files are not available on default Maven central repository.

I am describing on this article how to setup a first maven hadoop project for Cloudera CDH4 on eclipse. It is so simple to create a maven project for Hadoop that wasting time trying to build this plugin becomes totally useless. Moreover, it only provides the Old API for MapReduce. This plugin strongly depends on your environment (eclipse, ant, jdk) and hadoop distribution and version. I am sure I am not the only one who ever struggled with Hadoop eclipse plugin installation.
