Assignee: Branimir Lambov
> Race in sstable tracking can cause sstables to never be compacted
> -----------------------------------------------------------------
>
> Key: CASSANDRA-18342
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18342
> Project: Cassandra
> Issue Type: Bug
> Components: Local/Compaction
> Reporter: Branimir Lambov
> Assignee: Branimir Lambov
> Priority: Normal
>
> The sstable tracking by the compaction strategies permits a race between an
> sstable is added and removed that can cause a removed sstable to remain in
> the tracked list (when the add notification is received after the removal).
> This can cause reference leaks, because such {{SSTableReader}} s remain in
> the list forever, but if a strategy does not filter its sstable list through
> the live list (e.g. LCS in some code paths) it can also cause sstables that
> end up being selected to compact with these zombies to never compact
> (indicated by a "Could not acquire references for compacting SSTables..."
> message).
