Authorization Type	Parameter/Field	Comments/Description

Authorization Type	Parameter/Field	Comments/Description
SENTRY	Sentry Source Node	To use the Hive Source Node, select the Same As Hive Node option. Else, select the Other Node option.
	Sentry Node Host Name	If you selected the Other Node option above, enter the DNS name or IP address of the Sentry Node.
	Use different user account for accessing Sentry Node	Select the check box if you want to use a different user account (other than the login user) for accessing the Sentry node. If you select this option, you will be prompted to provide Username, Authentication Type, and Password/Shared Key for authentication.
	Sentry Library Path	Provide the absolute path for the Sentry library file jar inclusion to enable Sentry in Kyvos Manager. Refer to the Appendix for the Hadoop library and configuration paths for Cloudera.
	Sentry Configuration File	Upload the Sentry configuration file.
RANGER	Add Parameter	No additional configuration is required for this. NOTE: Kyvos does not support Column level security with Ranger, as Ranger does not provide the ability to integrate column-level security with a third party. The JDBC URL under HCatalog Parameters is mandatory for Ranger authorization while configuring the Hadoop ecosystem on the Kyvos Manager portal.
