Subject Re: Clearsnapshot Problem
Date Tue, 22 Mar 2011 20:40:08 GMT
AFAIK upgrade from 0.6.2 to 0.6.12 should be a straight forward rolling restart. Do check the
changes.txt file first and if you have a test env test it there. (The large gap in versions
makes me a little nervous).

If you feel it's reproducible (even sometimes) can you create a jira ticket ?  https://issues.apache.org/jira/browse/CASSANDRA

Windows gets less loving than *nix so any help is appreciated. 

Thanks
Aaron

In some cases there is no problem running a snapshot followed by a later clear snapshot (or
for that matter physical delete of the snapshot file).

are running fine except when trying to remove old snaphsot files. When running clearsnapshot
I get an error msg like below.  I can't remove any daily snapshot files. When trying to delete
the actual snapshot file os cmd file I get "access denied. File used by another process".
Seems CA or JRE is sitting on file?
