Steve Loughran commented on HADOOP-16255:
-----------------------------------------
I see your issue.
# It should just be matter of overriding the rename/3 call and having it move
the CRC tool; this is good to preserve the checksum too.
# patches with tests welcome...
# we're never going to do another 2.7.x release so saying it is affected isn't
going to make anyone care. I've tagged 2.8.5 as affected too
# now. can you upgrade spark's dependencies? please?
> ChecksumFS.Make FileSystem.rename(path, path, options) doesn't rename checksum

> Key: HADOOP-16255
> URL: https://issues.apache.org/jira/browse/HADOOP-16255
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Affects Versions: 2.8.5, 3.1.2
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
>
> ChecksumFS doesn't override FilterFS rename/3, so doesn't rename the checksum
> with the file.
> As a result, if a file is renamed over an existing file using rename(src,
> dest, OVERWRITE) the renamed file will be considered to have an invalid
> checksum -the old one is picked up instead.
