The cdap-site.xml file is the configuration file for a CDAP installation. Its properties and values determine the settings used by CDAP when starting and operating.
Any properties not found in an installation's cdap-site.xml will use a default parameter value defined in the file cdap-default.xml. It is located in the CDAP JARs and should not be altered.
Any of the default values (with the exception of those marked [Final]) can be overridden by defining a modifying value in the cdap-site.xml file, located (by default) either in <CDAP-HOME>/conf/cdap-site.xml (CDAP Sandbox) or /etc/cdap/conf/cdap-site.xml (Distributed CDAP).
Note: If you modify the cdap-site.xml file, you must restart your CDAP instance for the changes to take effect.

Kafka Server: All properties that begin with kafka.server. are passed to the CDAP Kafka service when it is started.
Security: For information on configuring the cdap-site.xml file, its security section, and CDAP for security, see the documentation Security section.
