Sandy Ryza commented on MAPREDUCE-5691:
---------------------------------------

In that case, adding network IO as a YARN resource and limiting it using 
cgroups might be a way to solve this problem as well.

> Throttle shuffle's bandwidth utilization

> In our hadoop cluster, a reducer of a big job can utilize all the bandwidth 
> during shuffle phase. Then any task reading data from  the machine which 
> running that reducer becomes very very slow.
> It's better to move DataTransferThrottler from hadoop-hdfs to hadoop-common. 
> And create a throttler for Shuffle to throttle each Fetcher.
