Default file locations for Installer-Services and package installations 

Locations when installing from the DataStax All-in-One Installer with Services option or package installations.

The default location of the files depend on how DataStax Enterprise is installed. The DataStax All-in-One Installer installs files differently depending on whether Services or No Services option is selected during installation. When Services is selected, the files are located in the same locations as package installations. When No Services are selected, the files are located in the same locations as the tarball installations.
