To view the details of a map/reduce script instance, from the Map/Reduce Script Status page, click View Details. Each row contains information about an individual map/reduce job that belongs to the script instance. A job always belongs to one of the stages of a map/reduce script, and there is at least one job per stage. There is exactly one job for each of the getInputData, shuffle, and summarize stages. The number of jobs for the map and reduce stages depends on concurrency limits and the number of yields.
