Speculative Execution in Hadoop refers to the process of executing multiple tasks for a single job in parallel, with the expectation that some of them may fail. The failed tasks are then re-executed using results from successful tasks or new input data as needed. Speculative execution helps reduce task completion time and improve overall system performance.
