David Manning created HBASE-26718: ------------------------------------- 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. -- This message was sent by Atlassian Jira (v8.20.1#820001)
