The Hadoop community voted last night to upgrade the core Hadoop softwareby upgrading YARN to a full blown Apache sub-project for Hadoop along with HDFS and MapReduce.

Hadoop YARN is basically MapReduce upgrade in an attempt to take Apache Hadoop beyond MapReduce for data-processing.

According to Hortonworks cofounder Arun Murthy blog post, Apache Hadoop YARN joins Hadoop Common (core libraries), Hadoop HDFS (storage) and Hadoop MapReduce (the MapReduce implementation) as the sub-projects of the Apache Hadoop which, itself, is a Top Level Project in the Apache Software Foundation. Until this milestone, YARN was a part of the Hadoop MapReduce project and now is poised to stand up on it’s own as a sub-project of Hadoop.

What Does This Mean for the Hadoop Community:

Hadoop has established itself as the big data platform of choice. Many big organizations are moving to Hadoop and those who don’t have a big data strategy will be left behind.

• Open Source Innovation v Stability: As an open source technology matures and becomes mainstream, it becomes increasingly important to balance community innovation and enterprise stability.

• Apache Hadoop Platform Completeness: Apache Hadoop with core set of related projects presents a wide array of functions to enable the ecosystem, ease operations and empower the developer with enterprise ready tools

• Apache Hadoop Maturity: Apache Hadoop has come a long way. Trusted and test versions of Hadoop is very important. Additionally, upgrades like YARN to the core is a great example of balancing the innovation and stability

• Community Stewardship: the Apache Hadoop community continues to push the platform forward. Hortonworks and Cloudera are working closely with the community and are stewards of the core so that it remains a viable solution for the enterprise.
