Description:
People often want to create tablespaces on separate disk to LCP/GCP. This is because of both more capacity and better splitting I/O load. To do so, we should specify the undo log/data file name using absolute path, but this is inconvenient. Please add a parameter to specify the directory to create tablespaces and undo logs, like DiskDataDir.

If possible, make it handle more than one directories. Because they want to create tablespaces on several disks by the same reason, more capacity and better splitting I/O load. In that case, ndbd creates files using different disks in turn. e.g. assume cluster has two directories, the first file is created under the first directory, the second file is created under the second directory, the third file is created under the first directory again...
