[jira] [Created] (HDFS-12102) VolumeScanner throttle dropped (fast scan enabled) when there is a corrupt block

Ashwin Ramesh created HDFS-12102:
------------------------------------

             Summary: VolumeScanner throttle dropped (fast scan enabled) when there is a corrupt block
                 Key: HDFS-12102
                 URL: https://issues.apache.org/jira/browse/HDFS-12102
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: datanode, hdfs
    Affects Versions: 2.8.2
            Reporter: Ashwin Ramesh
            Priority: Minor
             Fix For: 2.8.2


When the Volume scanner sees a corrupt block, it restarts the scan and scans the blocks at much faster rate with a negligible scan period. This is so that it doesn't take 3 weeks to report blocks since a corrupt block means increased likelihood that there are more corrupt blocks.
