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:
{code:title=RandomAccessReader.java|borderStyle=solid}
@Override
protected void finalize() throws Throwable {
deallocate();
super.finalize();
