> The testStandardDirs(org.apache.cassandra.db.DirectoriesTest) unit test
> always fails. This appears to be due to a commit by Yuki for CASSANDRA-10587
> which switched the SSTable descriptor to use the canonical path.
> From one of Yuki's comments in CASSANDRA-10587:
> "I ended up fixing Descriptor object to always have canonical path as its
> directory.
> This way we don't need to think about given directory is relative or absolute.
> In fact, right now Desctiptor (and corresponding SSTable) is not considered
> equal between Descriptor's directory being relative and absolute. (Added
> simple unit test to DescriptorTest)."
> The issue here is that canonical path will expand out differently than even
> absolute path. In this case /var/folders -> /private/var/folders. The unit
> test is looking for /var/folders/... but the Descriptor expands out to
> /private/var/folders and the unit test fails.
> Descriptor#L88 seems to be the real root cause.

> testStandardDirs(org.apache.cassandra.db.DirectoriesTest): FAILED

> I'm guessing given we went to canonicalPath() on purpose the "fix" here is to
> call .getCanonicalFile() on both expected Files generated (snapshotDir and
> backupsDir) for the junit assert.
