What are the features of yarn?

Features of YARN

  • High-degree compatibility: Applications created use the MapReduce framework that can be run easily on YARN.
  • Better cluster utilization: YARN allocates all cluster resources in an efficient and dynamic manner, which leads to better utilization of Hadoop as compared to the previous version of it.

What processes are part of Apache yarn?

YARN allows different data processing methods like graph processing, interactive processing, stream processing as well as batch processing to run and process data stored in HDFS. Therefore YARN opens up Hadoop to other types of distributed applications beyond MapReduce.

What are the advantages of yarn?

Benefits of YARN Utiliazation: Node Manager manages a pool of resources, rather than a fixed number of the designated slots thus increasing the utilization. Multitenancy: Different version of MapReduce can run on YARN, which makes the process of upgrading MapReduce more manageable.
