----------------------------------
Probably not an outright dupe of KUDU-668 but certainly worth reading that bug
for more context.
> Log block manager metadata doesn't handle partial truncation
> ------------------------------------------------------------
>
> Key: KUDU-1377
> URL: https://issues.apache.org/jira/browse/KUDU-1377
> Project: Kudu
> Issue Type: Bug
> Components: fs
> Affects Versions: 0.7.1
> Reporter: Mike Percy
> Assignee: Mike Percy
>
> If the log block manager's metadata file gets only partially written, this
> will result in failure to start up again. Since we are constantly appending,
> this is a problem since partial writes can occur when the disk fills up
> (among other potential error conditions like a system crash during a write).
> Pointer to the code in question:
> https://github.com/apache/incubator-kudu/blob/0.7.1/src/kudu/fs/log_block_manager.cc#L437
