> 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.
