-------------------------------------
Summary: HFileArchiver can remove referenced StoreFiles from the
archive
Key: HBASE-26718
URL: https://issues.apache.org/jira/browse/HBASE-26718
Project: HBase
Issue Type: Bug
Components: Compaction, HFile, snapshots
Affects Versions: 2.0.0, 3.0.0-alpha-1, 1.0.0
Reporter: David Manning
Assignee: David Manning
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.
