Prefer IntelliJ IDEA over Eclipse? We’ve got you covered: learn how to get ready to contribute to Apache Hadoop via an IntelliJ project.
It’s generally useful to have an IDE at your disposal when you’re developing and debugging code. When I first started working on HDFS, I used Eclipse, but I’ve recently switched to JetBrains’ IntelliJ IDEA (specifically, version 13.1 Community Edition).
My main motivation was the ease of project setup in the face of Maven and Google Protocol Buffers (used in HDFS).
