Categories: Hadoop How-to Tools

Prefer IntelliJ IDEA over Eclipse? We’ve got you covered: learn how to get ready to contribute to Apache Hadoop via an IntelliJ project.

How-to: Configure Eclipse for Hadoop Contributions

While it is perfectly fine to use a text editor to modify Java source, modern IDEs simplify navigation and debugging of large Java projects like Hadoop significantly. Eclipse is a popular choice thanks to its broad user base and multitude of available plugins.

This post covers configuring Eclipse to modify Hadoop’s source. (Developing applications against CDH using Eclipse is covered in a different post.) Hadoop has changed a great deal since our previous post on configuring Eclipse for Hadoop development;

Last month, Apache Crunch became the fifth project (along with Sqoop, Flume, Bigtop, and MRUnit) to go from Cloudera’s github repository through the Apache Incubator and on to graduate as a top-level project within the Apache Software Foundation. As the founder of the project and a newly minted Apache VP,
