Job History Log Analyzer parses and analyzes history logs of map-reduce jobs.
History logs contain information about execution of jobs, tasks, and attempts.

success or failure of jobs, tasks and attempt.
The analyzer calculates _per hour slot utilization_ and _pending times_ on
clusters running map-reduce jobs.
