      Description

      Similar to HDFS-3170 on the write side, we should improve the metrics that are generated on the DN for read latency. We should have separate metrics for the time spent in transferTo vs waitWritable so that it's easy to distinguish slow local disks from slow readers on the other end of the socket.
