ColumnStore doesn't allow or support changing the location of the data directories in either the Columnstore.xml file or the my.cnf

This can be done using softlinks where you map the database directories to a new location

There is an open JIRA to make this enhancement in a future load, but its hasnt been placed in the roadmap at this time.
