> Key: HBASE-26718
> URL: https://issues.apache.org/jira/browse/HBASE-26718
> Project: HBase
> Issue Type: Bug
> Components: Compaction, HFile, snapshots
> Affects Versions: 0.95.0, 1.0.0, 3.0.0-alpha-1, 2.0.0
> Reporter: David Manning
> Assignee: David Manning
> Priority: Major

> There is a comment in {{HFileArchiver#resolveAndArchiveFile}}:
> {code:java}
> // if the file already exists in the archive, move that one to a timestamped
> backup. This is a
> // really, really unlikely situtation, where we get the same name for the
> existing file, but
> // is included just for that 1 in trillion chance.
> {code}
> In reality, we did encounter this frequently enough to cause problems. More
> details will be included and linked in a separate issue.
> But regardless of how we get into this situation, we can consider a different
> approach to solving it. If we assume store files are immutable, and a store
> file with the same name and location already exists in the archive, then it
> can be safer to assume the file was already archived successfully, and react
> accordingly.
