      Description

      There is some incorrect object using in DataNodeVolumeMetrics, writeIoRate is never used and syncIoRate should be replaced by writeIoRate in the following code:

      // Based on writeIoRate
      public long getWriteIoSampleCount() {
        return syncIoRate.lastStat().numSamples();
      }
      
      public double getWriteIoMean() {
        return syncIoRate.lastStat().mean();
      }
      
      public double getWriteIoStdDev() {
        return syncIoRate.lastStat().stddev();
      }
