----------------------------------

             Summary: In the HFileBlock class, the log printing fspread/fsread 
cost time unit should be milliseconds
                 Key: HBASE-27099
                 URL: https://issues.apache.org/jira/browse/HBASE-27099
             Project: HBase
          Issue Type: Bug
          Components: HFile
    Affects Versions: 2.4.12, 2.3.7, 3.0.0-alpha-2, 2.5.1
            Reporter: Xiao Zhang
            Assignee: Xiao Zhang


In the HFileBlock class

 
{code:java}
protected HFileBlock readBlockDataInternal(FSDataInputStream is, long offset, 
long onDiskSizeWithHeaderL, boolean pread, boolean verifyChecksum, boolean 
updateMetrics, boolean intoHeap) throws IOException {
  ...
  long startTime = EnvironmentEdgeManager.currentTime();
  ...
  long duration = EnvironmentEdgeManager.currentTime() - startTime;
  if (updateMetrics) {
    HFile.updateReadLatency(duration, pread);
  }
  ...
  LOG.trace("Read {} in {} ns", hFileBlock, duration);
  ...
}{code}
But Environment EdgeManager.currentTime returns milliseconds.
