Apache MRUnit Is Now A Top Level Project

Categories: MapReduce

This posted was originally posted to the Apache Software Foundation MRUnit blog.

The Apache MRUnit team has graduated from the Apache Incubator to an Apache TLP (Top Level Project)! MRUnit is a Java library that helps developers unit test Apache Hadoop MapReduce jobs. Unit testing is a technique for improving project quality and reducing overall costs by writing a small amount of code that can automatically verify the software you write performs as intended. This is considered a best practice in software development since it helps identify defects early, before they're deployed to a production system.

In its monthly meeting in May of 2012, the board of Apache Software Foundation (ASF) resolved to grant a Top-Level Project status to Apache MRUnit, thus graduating it from the Incubator. This is a significant milestone in the life of MRUnit, which has come a long way since its inception as a Hadoop Contrib project in HADOOP-5518 contributed by Aaron Kimball.
