Yarn stands for Yet Another Resource Negotiator. It is the resource management layer of Hadoop. The Yarn was launched in Hadoop 2.x. Yarn provides many data processing engines like graph processing, batch processing, interactive processing, and stream processing to execute and process data saved in the Hadoop Distributed File System. Yarn also offers job scheduling. It extends the capability of Hadoop to other evolving technologies so that they can take good advantage of HDFS and economic clusters.
Apache Yarn is the data operating method for Hadoop 2.x. It consists of a master daemon known as â€œResource Manager,â€ a slave daemon called node manager, and Application Master.
