> Job History Log Analyzer parses and analyzes history logs of map-reduce jobs.
> History logs contain information about execution of jobs, tasks, and
> attempts. The tool focuses on submission, launch, start, and finish times, as
> well as the success or failure of jobs, tasks and attempt.
> The analyzer calculates _per hour slot utilization_ and _pending times_ on
> clusters running map-reduce jobs.
