Joshua McKenzie updated CASSANDRA-8544:
---------------------------------------
Attachment: 8544_v1.txt
If turning off AV and Windows Search consistently fixes this I consider this an
external/environment problem and not a problem with our code-base w/regards to
stopping. Pre 3.0 (and w/memory-mapped I/O when we go back down that route),
file sharing violations like this from outside programs are, by default, a
problem we're going to stop the database for rather than allowing failed
deletions to potentially fill a drive on a node. If you'd prefer to allow the
system to continue you can reference the following:
[one|http://www.datastax.com/documentation/cassandra/2.0/cassandra/configuration/configCassandra_yaml_r.html]
-
[two|http://www.datastax.com/dev/blog/handling-disk-failures-in-cassandra-1-2].
At the very least, you need to exclude your cassandra data and logs folder from
AV scanning and also [remove it from
indexing|http://windows.microsoft.com/en-us/windows/improve-windows-searches-using-index-faq#1TC=windows-7].
Attaching a v1 that wraps the NPE and instead throws an FSReadError and points
to log file for more information, since our original NPE error isn't terribly
useful.
