Jothi Padmanabhan updated MAPREDUCE-956: ---------------------------------------- Component/s: task Affects Version/s: 0.21.0 > Shuffle should be broken down to only two phases (copy/reduce) instead of > three (copy/sort/reduce) > -------------------------------------------------------------------------------------------------- > > Key: MAPREDUCE-956 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-956 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: task > Affects Versions: 0.21.0 > Reporter: Jothi Padmanabhan > > For the progress calculations and displaying on the UI, shuffle, in its > current form, is decomposed into three phases (copy/sort/reduce). Actually, > the sort phase is no longer applicable. I think we should just reduce the > number of phases to two and assign 50% weight-age to each of copy and reduce > phases.
