LEM project

Active development years: 2013

Summary

For now: simple tests to verify, that 'append' and 'pluggable block placement policy' hadoop's features work. Expect more interesting stuff here later. :)

Working with source code

You will need:

• Java 6 JDK: www.oracle.com/technetwork/java/javase/downloads/index.html
• gradle 1.6 (or newer) build tool: www.gradle.org/
• fabric: http://docs.fabfile.org/en/1.7/
• (optional - if you want to setup the cluster) whirr: http://whirr.apache.org/

Compilation

Just do gradle build in root directory. gradle will download all required dependencies and compile classes

Editing

I strongly recommend IntelliJ for editing the source. The community edition is free for non-commercial purposes and can be downloaded here: www.jetbrains.com/idea/ Execute gradle idea, which will generate all required files. Then open the project in IntelliJ and enjoy!

Running the features tests

• using in-memory hadoop cluster - gradle runInMemory
• using real hadoop cluster (you need to set up cluster yourself) - gradle runOnHadoop -Dmaster=masterAddress, where masterAddress is an external address of the master machine in your cluster (can be localhost too)
