[jira] [Created] (HDFS-13111) Close recovery may incorrectly mark blocks corrupt

Daryn Sharp created HDFS-13111:
----------------------------------

             Summary: Close recovery may incorrectly mark blocks corrupt
                 Key: HDFS-13111
                 URL: https://issues.apache.org/jira/browse/HDFS-13111
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode
    Affects Versions: 2.8.0
            Reporter: Daryn Sharp


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.
