Our objective was to build a system that would provide an intuitive insight into Spark jobs that not just provides visibility but also codifies the best practices and deep experience we have gained after years of debugging and optimizing Spark jobs. The main design objectives were to be
– Intuitive and easy – Big data practitioners should be able to navigate and ramp quickly
– Concise and focused – Hide the complexity and scale but present all necessary information in a way that does not overwhelm the end user
– Batteries included – Provide actionable recommendations for a self service experience, especially for users who are less familiar with Spark
– Extensible – To enable additions of deep dives for the most common and difficult scenarios as we come across them
The tool looks pretty interesting and I’m hoping it will be part of the open source suite at Cloudera.
