> Key: CASSANDRA-7234
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7234
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Tyler Hobbs
> Priority: Minor
> Labels: compaction
> Fix For: 2.0.9
>
> Attachments: 0001-reference-sstable-before-populating-keycache.patch
>
>
> In CompactionTask.java, after a compaction finishes, we do this:
> {code}
> replaceCompactedSSTables(toCompact, sstables);
> // TODO: this doesn't belong here, it should be part of the reader to
> load when the tracker is wired up
> for (SSTableReader sstable : sstables)
> sstable.preheat(cachedKeyMap.get(sstable.descriptor));
> {code}
> The problem is that if the table was dropped, {{replaceCompactedSSTables}}
> will release its references on the new {{sstables}}, resulting in them being
> closed.
