BigSift combines insights from automated fault isolation in software engineering and data provenance in database systems to find a minimum set of failure-inducing inputs. It redefines data provenance for the purpose of debugging using a test oracle function and implements several unique optimizations, specifically geared towards the iterative nature of automated debugging workloads.
BigSift exposes an interactive web interface where a user can monitor a big data analytics job running remotely on the cloud, write a user-defined test oracle function, and then trigger the automated debugging process.
BigSift also provides a set of predefined test oracle functions, which can be used for explaining common types of anomalies in big data analytics
