> Key: KUDU-1978
> URL: https://issues.apache.org/jira/browse/KUDU-1978
> Project: Kudu
> Issue Type: Bug
> Components: fs
> Affects Versions: 1.1.0
> Reporter: Adar Dembo
> Assignee: Adar Dembo
> Priority: Critical
> Fix For: 1.4.0
>
>
> When faced with repeated sequences of misaligned blocks, the LBM may corrupt
> one while deleting its neighbor. This is due to the aligning behavior in the
> hole punching code: aligning up to the nearest filesystem block boundary is
> incorrect behavior if the following block is misaligned.
> Note: misaligned blocks in the LBM are incredibly rare. To see them, you must
> have been victimized by KUDU-1793. Repeated sequences of misaligned blocks
> are even rarer; I'm not even sure if they're possible.
