Default file locations for tarball and Installer-No Services installations

The default location of the files depends on how you install DataStax Enterprise (DSE):

The files are in the same locations for Package installations and when the Services is selected using the DataStax Installer.
The files are in the same locations for Tarball and when No Services is selected using the DataStax Installer.

Default installation location

The default installation_location depends on whether you install DSE by using the DataStax Installer or from the binary tarball:

Installer-No Services: /usr/share/dse
Tarball installation: The location where you extracted DSE.
