> When you run the DirectoriesTest as a normal user, it passes because it fails to create the 'bad' directory:
> {noformat}
>     [junit] ------------- Standard Error -----------------
>     [junit] ERROR 16:16:18,111 Failed to create /tmp/cassandra4119802552776680052unittest/ks/bad directory
>     [junit]  WARN 16:16:18,112 Blacklisting /tmp/cassandra4119802552776680052unittest/ks/bad for writes
>     [junit] ------------- ---------------- ---------------
> {noformat}
> But when you run the test as root, it succeeds in making the directory, causing an assertion failure that it's unwritable:
> {noformat}
>     [junit] Testcase: testDiskFailurePolicy_best_effort(org.apache.cassandra.db.DirectoriesTest):       FAILED
>     [junit] 
>     [junit] junit.framework.AssertionFailedError: 
>     [junit]     at org.apache.cassandra.db.DirectoriesTest.testDiskFailurePolicy_best_effort(DirectoriesTest.java:199)
> {noformat}
> It seems to me that we shouldn't be relying on failing the make the directory.  If we're just going to test a nonexistent dir, why try to make one at all?  And if that is supposed to succeed, then we have a problem with either the test or blacklisting.
