> 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
> Assignee: Ahmed Hussein
> Priority: Minor
> Attachments: HDFS-12102-001.patch, HDFS-12102-002.patch,

>
> 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.
