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 is YARN and features of YARN?

YARN is a large-scale, distributed operating system for big data applications. The technology is designed for cluster management and is one of the key features in the second generation of Hadoop, the Apache Software Foundation’s open source distributed processing framework.

What are the two main components of YARN?

It has two parts: a pluggable scheduler and an ApplicationManager that manages user jobs on the cluster. The second component is the per-node NodeManager (NM), which manages users’ jobs and workflow on a given node.

Is Hadoop written in Java?

The Hadoop framework itself is mostly written in the Java programming language, with some native code in C and command line utilities written as shell scripts. Though MapReduce Java code is common, any programming language can be used with Hadoop Streaming to implement the map and reduce parts of the user’s program.
