Subject [jira] [Commented] (CASSANDRA-8390) The process cannot access the file because it is being used by another process
Date Fri, 12 Dec 2014 18:03:13 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14244532#comment-14244532
] 

Joshua McKenzie commented on CASSANDRA-8390:
--------------------------------------------

Upped to 40 iterations, ran 3 times w/out AV and then put windows defender on the box, activated,
mmap on index files and ran up to 120 iterations and still can't reproduce.  I'm on spinning
disk here w/some other factors so that may play into it if this is a timing issue.

The failure to delete within SSTableDeletingTask after successfully deleting the data file
is fairly unique to this ticket as far as I know, and while it could indicate logic errors
in SSTR.tidy / SSTR.scheduleTidy w/regards to unmapping mmap'ed segments, I'd expect to see
this show up with more frequency if it was a logical error such as that.

Something else on that system has a handle to that file open and we can't control the ecosystem
outside Cassandra which has shown to be a headache on Windows.  If either of you could reproduce
and run [Handle|http://technet.microsoft.com/en-us/sysinternals/bb896655.aspx] on your system,
preferably with admin credentials on the command-prompt, and search for one of these files
you're getting an error on it may help us narrow this down.

I haven't tried running from within Upsource - [~alexander_radzin]: are you running C* from
within upsource as well or running it natively from cassandra.bat?
