摘要: Large-scale distributed systems, like MapReduce, are increasingly being used, but debugging such systems is still very difficult. In this paper, we propose D3, a new system that answers diverse queries by processing logs formally and efficiently. D3 specifies concisely in declarative language executes the fashion, thereby lowering overhead bandwidth consumed. We demonstrate effectiveness of our design on local cluster with Hadoop, an open-source MapReduce frame-
