------------------------------------------

             Summary: Fix dtests on WIndows
                 Key: CASSANDRA-9418
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9418
             Project: Cassandra
          Issue Type: Bug
            Reporter: Joshua McKenzie
            Assignee: Joshua McKenzie
             Fix For: 2.2.x


There's a variety of infrastructural failures within dtest w/regards to windows that are causing tests to fail and those failures to cascade.

Error: failure to delete commit log after a test / ccm cluster is stopped:
{noformat}
Traceback (most recent call last):

    onerror(os.remove, fullname, sys.exc_info())

    os.remove(fullname)
WindowsError: [Error 5] Access is denied: 'c:\\temp\\dtest-4rxq2i\\test\\node1\\commitlogs\\CommitLog-5-1431969131917.log'
{noformat}

Cascading error: implication is that tests aren't shutting down correctly and subsequent tests cannot start:
{noformat}

{noformat}

I've also seen (and am debugging) an error where a node just fails to start via ccm.

I'll update this ticket with PR's to dtest or other observations of interest.
