    Description

      We are seeing a performance regression in DFSIO write benchmark, possibly due to Hadoop-1707.

      Here is the data:

      • Aggregate cluster throughput went from 0.30G to 0.14G with 39 concurrent clients, on 20 nodes
      • Aggregate cluster throughput went from 1.15G to 0.85G with 39 concurrent clients, on 100 nodes
