Introduction
Greetings, dear reader! Today, we’ll discuss one of the most powerful tools in the world of big data and distributed processing: the Apache YARN Timeline Server. But before diving into the technical details, let’s step back and understand the context and use case of this powerful system.
In today’s world, data is generated at an enormous pace. Companies are investing heavily in data collection and analysis to gain a competitive edge. But collecting data is only half the battle; making sense of this data and generating valuable insights is the other half.
Here’s where Apache YARN Timeline Server comes into play. It’s a powerful tool that helps manage distributed processing, making it easy to track and analyze data, which is generated by multiple sources. It provides organizations with a comprehensive view of job execution history, leading to faster and more efficient analysis.
In this article, we’ll explore the in’s and out’s of Apache YARN Timeline Server and its advantages and disadvantages. Let’s get started!
What is Apache YARN Timeline Server?
Apache YARN Timeline Server is a component of Apache Hadoop YARN, which manages resources and scheduling for distributed processing jobs. Apache YARN provides a central platform to manage, monitor, and schedule distributed processing jobs across thousands of nodes in a cluster.
The Timeline Server is designed to capture job execution history and provide a comprehensive view of the timeline data to users. It acts as a single source of truth for all the job execution data and provides a unified view for various tools and applications. The data can be accessed from REST APIs and can be visualized using various tools and libraries provided by Apache Hadoop YARN.
