Subject [jira] [Commented] (CASSANDRA-7195) ColumnFamilyStoreTest unit tests fails on Windows
Date Thu, 15 May 2014 00:28:11 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7195?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13998313#comment-13998313

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.
