--------------------------

URL: https://issues.apache.org/jira/browse/CASSANDRA-2669
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 0.7.6
Reporter: Daniel Doubleday

After scrubbing I find that cassandra process still holds file handles to the
deleted sstables:
{noformat}
root@blnrzh047:/mnt/cassandra# jps

I guess there's a missing dataFile.close() in CompactionManager:648
