Bug #46243 --initial does not clear disk data files although filesystemDD is set

Description:
Having specified

FileSystemDD=/data/mysqlcluster/

does not clear the data files and undo files for disk data although it should according to the docs:

http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-ndbd-definition.html#mysql-cluster-pa...

How to repeat:
1) create a logfile group
2) create a table space
3) stop cluster
4) start cluster with --initial

Suggested fix:
-

problem was that FileSystemPath[DD/DataFiles/UndoFiles] was not cleared
*iff* it was equal to FileSystemPath (i.e had identical value)

the patch fixes this problem...

A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:

Hi,
 tested that it works.. and it did.
Thanks!

Documented bugfix in the NDB-6.2.19, 6.3.26, and 7.0.7 changelogs as follows:

        If the value set in the config.ini file for FileSystemPathDD,
        FileSystemPathDataFiles, or FileSystemPathUndoFiles was
        identical to the value set for FileSystemPath, that parameter
        was ignored when starting a data node with --initial. As a
        result, the Disk Data files in the corresponding directory were
        not removed when performing an initial start of the affected
        data node or data nodes.
