Introduction to Yarn and its Features

Yarn was actually Facebook’s attempt to make up for npm deficiencies. Technically, Yarn was not created instead of npm because it still uses npm registry modules, but a new installer that still uses the npm structure. In simpler language, the registry is still the same registry, but the installation method is different. Since Yarn and npm have a package set, you will not need to make major changes if you want to go from Yarn to npm or vice versa.

Yarn enables you to manage resources and plan jobs in Hadoop. Here are some of the features of Yarn:

1. Multi-tenancy

With this feature, you can use multiple open source and dedicated data access engines for batch, interactive, and real-time access to the same dataset.

2. Cluster utilization

You can allocate cluster resources dynamically to improve resource usage.

3. Multiple resource types

You can use several different sources such as memory, CPU, and GPU.

4. Scalability

You can significantly improve data center processing power by using Yarn. ResourceManager YARN focuses exclusively on scheduling and maintains its speed by extending clusters to thousands of petabytes of data management nodes.

5. Compatibility

The MapReduce applications developed for Hadoop 1 run on YARN without interrupting any existing processes. YARN maintains API compatibility with the previous stable version of Hadoop.
