How Yarn is Used for Big Data Processing

Yarn has become an essential tool in big data processing as it enables multiple data processing engines to run and share resources effectively. In this article, we will delve deep into the topic of how yarn is used in big data processing, exploring its benefits, use cases, and more.

The Background on Yarn

Yarn, short for Yet Another Resource Negotiator, is a distributed parallel computing framework. It was developed by Apache Hadoop for large-scale data processing. Yarn separates the resource management and job scheduling functions into separate daemons, enabling different applications to share a common resource pool. In simpler terms, Yarn allows multiple Hadoop application programs to run across a shared resource pool.

Benefits of Yarn in Big Data Processing

Yarn has numerous benefits in big data processing, including but not limited to:

1. Improved resource utilization

Yarn enables efficient utilization of resources by sharing among different applications, thereby reducing idle resources.

2. Scalability

Yarn supports the scaling of resources to meet the demands of different applications by dynamically allocating resources based on application requirements.

3. Better security

Yarn provides support for securing sensitive information in both storage and job execution by enforcing access control and auditing features.

4. Flexibility

Yarn’s architecture provides the flexibility to add new applications without compromising previously running applications.

Use Cases for Yarn in Big Data Processing

Yarn plays a crucial role in powering big data processing in various industries. Below are some notable use cases of Yarn in different industries:

1. Healthcare

Yarn is used in healthcare applications to process vast amounts of patient data efficiently and quickly, enabling doctors to make informed decisions based on real-time data, thereby improving patient outcomes.

2. Retail

Yarn is utilized in retail to analyze customer behavior and preferences, enabling retailers to make data-driven decisions to improve customer satisfaction and generate more revenue.

3. Finance

In the finance industry, Yarn is used to analyze transaction data, detect fraud, and identify relevant trends, enabling financial institutions to mitigate risks and improve customer experience.

Conclusion

Yarn has become a popular tool in big data processing, enabling seamless sharing of resources among different programs, thereby improving resource utilization, scalability, security, and flexibility. The use cases for Yarn span across various industries, from healthcare to retail to finance. As the world of big data processing continues to evolve, Yarn is undoubtedly poised to play an even more significant role in powering data processing engines.
