hadoop.proxyuser.kyvos.groups
Go to Sentry service of Cloudera Manager and add kyvos in the service.allow.connect property.
On the navigation pane, click Security > Hadoop Authorization.

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. |
