> 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.
