> {code}
> But if you change the path configuration or migrate the data to another
> cluster which node name is different or original host cannot be reached, you
> will meet problems in reusing it, like rebuilding and merge dictionary or
> transfer column from dictionary in building cube, for the dictionary info
> cannot be found.
