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.
