As TripAdvisor moves increasing amounts of data into Hadoop and Hive, the need for simplifying, controlling, and expanding access to this data has grown. Having reviewed existing solutions without finding what we needed, we began working on our own solution to meet our specific goals and use-cases. The Hive Query Tool (HQT) is a web interface that allows anybody to configure and run Hive queries without requiring client-side installation or even knowledge of the query language. Users familiar with HQL can add sophisticated and highly customizable queries with a flexible and powerful template system. A primary innovation, the template system, allows one to define the inputs available to the end-user, validation checks, and what HQL to generate, easily and concisely. We plan to release the code as open-source. This talk will discuss: – The features of the HQT and how it is used for business intelligence – The challenges it was built to meet and how its design and architecture addresses them – Installing and running an HQT server – How to use, customize, and expand the template system – Known limitations and issues – Future plans and features
