Aleksey Yeschenko updated CASSANDRA-6283: ----------------------------------------- Labels: newbie patch test (was: newbie patch performance test) > 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?
