Hello, I have noticed that for the simple wordcount example on 60GB of data distributed across 3 data nodes and with 10 tasktrackers (including the 3 data nodes) the copy-rate of reducers decreases as the job progresses. It starts with ~10MB/s and by the end (95% mappers complete) is ~2MB/s
Is there any obvious answer to this? Looking forward to your reply! patektek
