[~Andie78] Do you you see "can't delete" exceptions only of files like
{{\snapshots\dac98330-47bc-11e3-b167-eb1c24a59bb8\}} (i.e. from a snapshots
subfolder) or with other files as well?
I suspect that https://issues.apache.org/jira/browse/CASSANDRA-4050 causes
{{doValidationCompaction}} to fail (and entire RepairSession as well). - as far
as I understand REPAIR without "parallel" option (which is default behavior)
creates a snapshot, validates and then deletes the snapshot. The last step
fails on WIndows

> Windows 7 data files keept open / can't be deleted after compaction.

> Key: CASSANDRA-6283
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6283
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: Windows 7 (32) / Java 1.7.0.45
> Reporter: Andreas Schnitzerling
> Priority: Critical
> Labels: newbie, patch, test
> Fix For: 2.0.3, 2.1
>
> Attachments: screenshot-1.jpg, system.log

>
> Files cannot be deleted, patch CASSANDRA-5383 (Win7 deleting problem) doesn't
> help on Win-7 on Cassandra 2.0.2. Even 2.1 Snapshot is not running. The cause
> is: Opened file handles seem to be lost and not closed properly. Win 7
> blames, that another process is still using the file (but its obviously
> cassandra). Only restart of the server makes the files deleted. But after
> heavy using (changes) of tables, there are about 24K files in the data folder
> (instead of 35 after every restart) and Cassandra crashes. I experiminted and
> I found out, that a finalizer fixes the problem. So after GC the files will
> be deleted (not optimal, but working fine). It runs now 2 days continously
> without problem. Possible fix/test:
> I wrote the following finalizer at the end of class
> org.apache.cassandra.io.util.RandomAccessReader:
> @Override
> protected void finalize() throws Throwable {
> deallocate();
> super.finalize();
> }
> Can somebody test / develop / patch it? Thx.
