-------------------------------------------------------------------
I hit this on (and confirmed the fix against) 2.2.7, but the problem appears to
still exist on trunk and the fix is trivial and cherry-picks nicely:

> org.apache.cassandra.io.sstable.Descriptor constructor calls
> directory.getCanonicalFile() on the File directory passed to it. If this is
> a symlink, then the assert in DirectoriesTest.testStandardDirs fails, because
> the File we compare it against contains the symlink, not the canonical path,
> and File.equals(File other) compares the abstract paths themselves (without
> resolving symlinks).
