java.lang.RuntimeException: alluxio.exception.FileAlreadyExistsException: Mount point /foo already existsThis is because when we replay rm -R, we don't remove mount points. So on replay, we see an existing mount point being re-created.
To fix this, we should update the replay path for rm -R so that it removes mount points.
