We have discussed a high level view of YARN Architecture in my post on Understanding Hadoop 2.x Architecture but YARN it self is a wider subject to understand. Keeping that in mind, we’ll about discuss YARN Architecture, it’s components and advantages in this post. Continue reading “YARN Architecture and Components”
