> Measure bw of a single copy call and display the correct aggregated bw

> Key: MAPREDUCE-5873
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5873
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 2.3.0

>
> Currently ShuffleScheduler in ReduceTask JVM status displays bandwidth. Its
> definition however is confusing because it captures the time where there is
> no copying because there is a pause between when new wave of map outputs is
> available.
> current bw is definded as (bytes copied so far) / (total time in the copy
> phase so far)
> It would be more useful
> 1) to measure bandwidth of a single copy call.
> 2) display aggregated bw as long as there is at least one fetcher is in the
> copy call.
