What are two benefits of YARN?

YARN has many advantages over MapReduce (MRv1). 1) Scalability – Decreasing the load on the Resource Manager(RM) by delegating the work of handling the tasks running on slaves to application Master, RM can now handle more requests than Job tracker facilitating addition of more nodes.

What is YARN used for?Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, or ropemaking. Thread is a type of yarn intended for sewing by hand or machine.

What benefits did YARN bring in Hadoop 2.0 and how did it solve the issues of MapReduce v1?

YARN provides central resource manager. With YARN, you can now run multiple applications in Hadoop, all sharing a common resource. Yarn can even run application that do not follow MapReduce model.

How does YARN improve the Hadoop framework?

Hadoop YARN Architecture

  • Scalability: The scheduler in Resource manager of YARN architecture allows Hadoop to extend and manage thousands of nodes and clusters.
  • Compatibility: YARN supports the existing map-reduce applications without disruptions thus making it compatible with Hadoop 1.0 as well.

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.
