As many of you may recall, YARN was first released in October 2013 and gathered a lot of buzz in the later part of the year. On February 20th, the community voted to release the next version of YARN with Hadoop 2.3.0. We are delighted at the progress that has been made with YARN in particular. Here are the Hadoop 2.3.0 release notes from the Apache Hadoop website. As you can see, a lot of YARN issues were fixed, helping YARN advance in its journey to becoming a stable and production-ready system.
I'm also happy to share that Apache Hadoop 2.3.0 will be included in the upcoming version of the YARN beta release from MapR. MapR is the only platform that delivers a general purpose framework for storage and processing on Hadoop. This provides a best-of-both-worlds approach, and expands the use cases that Hadoop can accommodate. With MapR, customers will be able to run the current MapReduce v1 workloads and YARN scheduler on the same node in the cluster, thereby making the migration to YARN simpler, and on a schedule based on the customer's business requirements.
