> For a map task of a map-reduce job, the progress bar is (logically) split into 2 distinct phases
> 1. Map Phase
> 2. Sort Phase
> The map phase manages 66% of the overall tasks progress while the sort phase governs the rest i.e 33%. 
> For a map task of a map-only job, there is no sort phase. Hence the entire map phase should govern 100% of the task's progress. Currently, the progress bar is split divided into 66%-33% irrespective of whether the job has reducers or not (i.e whether there is a sort phase or not).
