    Description
    org.apache.hadoop.hdfs.server.datanode.metrics.DataNodeDiskMetrics
    This class detects and maintains DataNode disk outliers and their latencies for different ops (metadata, read, write).
    org.apache.hadoop.hdfs.server.datanode.metrics.DataNodeDiskMetrics.DiskLatency
    This structure is a wrapper over disk latencies.
