Spark Inspector

The three-dimensional view of the application's interface

In-depth Performance Analysis: Spark Inspector provides detailed insights into the execution of Spark jobs, allowing you to analyze stages, tasks, and resource usage. It helps you identify performance bottlenecks and understand the behavior of your Spark application. Visual Timelines: The web-based interface of Spark Inspector presents timelines that visualize the execution data, making it easier to spot long-running stages, data skew, and resource contention. This visual representation enhances the understanding of your application's performance characteristics. Optimizing Spark Applications: By leveraging the insights provided by Spark Inspector, you can make informed optimizations to your Spark application. It enables you to identify areas for improvement, such as optimizing data partitioning, caching strategies, or identifying slow tasks for further investigation. Iterative Development Process: Spark Inspector supports an iterative development process by allowing you to make optimizations, re-run your Spark application, and compare the results. This iterative approach helps you fine-tune your application and achieve better performance. Third-Party Tool Support: Spark Inspector is a popular third-party tool specifically designed for Spark application debugging and optimization. It complements the existing Spark ecosystem and provides additional capabilities beyond the built-in monitoring and debugging tools.

Spark Inspector allows developers to inspect and monitor the app’s view hierarchy, network requests, and memory usage in real-time. This helps in identifying and resolving any potential bottlenecks or memory leaks.
