Joshua McKenzie commented on CASSANDRA-7195:
--------------------------------------------
Looks like File.exists() in java will return false if you don't have
permissions to a file or if a file is pending deletion on windows. Some
digging turned up
[this|http://stackoverflow.com/questions/3764072/c-win32-how-to-wait-for-a-pending-delete-to-complete].
I ran a process monitor trace against the ColumnFamilyStore test and see the
following during the test when I try to access the file to query permissions
and/or list() against the directories for the cfs:

SUCCESS
{code}
This is consistently happening against a specific ka-10 idx and data file.
Another interesting point is that on the 1/10 runs that succeed, I see an
SSTableDeletingTask for that file whereas I *don't* see a deleting task on runs
that fail.
