[jira] [Commented] (HDFS-13111) Close recovery may incorrectly mark
blocks corrupt
[ https://issues.apache.org/jira/browse/HDFS-13111?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16722727#comment-16722727 ]

----------------------------------------
I suspect HDFS-10240, which was fixed recently, sounds similar from the description.

> Affects Versions: 2.8.0

> Close recovery can leave a block marked corrupt until the next FBR arrives from one of the DNs. The reason is unclear but has happened multiple times when a DN has io saturated disks.
