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.
