[jira] [Created] (MAPREDUCE-2511) Progress reported by map tasks of
a map-only job is incorrect
Progress reported by map tasks of a map-only job is incorrect
-------------------------------------------------------------
Key: MAPREDUCE-2511
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2511
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 0.23.0
Reporter: Amar Kamat
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).
