> VolumeScanner reports write-in-progress replicas as corrupt incorrectly
> -----------------------------------------------------------------------
>
> Key: HDFS-11160
> URL: https://issues.apache.org/jira/browse/HDFS-11160
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Environment: CDH5.7.4
> Reporter: Wei-Chiu Chuang
> Assignee: Wei-Chiu Chuang
> Attachments: HDFS-11160.001.patch, HDFS-11160.002.patch,
> HDFS-11160.003.patch, HDFS-11160.004.patch, HDFS-11160.branch-2.patch,
> HDFS-11160.reproduce.patch
>
>
> Due to a race condition initially reported in HDFS-6804, VolumeScanner may
> erroneously detect good replicas as corrupt. This is serious because in some
> cases it results in data loss if all replicas are declared corrupt. This bug
> is especially prominent when there are a lot of append requests via
> HttpFs/WebHDFS.
> We are investigating an incidence that caused very high block corruption rate
> in a relatively small cluster. Initially, we thought HDFS-11056 is to blame.
> However, after applying HDFS-11056, we are still seeing VolumeScanner
> reporting corrupt replicas.
> It turns out that if a replica is being appended while VolumeScanner is
> scanning it, VolumeScanner may use the new checksum to compare against old
> data, causing checksum mismatch.
> I have a unit test to reproduce the error. Will attach later. A quick and
> simple fix is to hold FsDatasetImpl lock and read from disk the checksum.
