Interaction with Hive and Impala

Hive

In multi-user security mode, all interactions between DSS and Hive happen through HiveServer2

HiveServer2 itself uses Sentry or Ranger to authorize access to Hive databases and tables.

DSS does not push authorization rules to Sentry or Ranger nor does it pull authorization rules from these systems.

Thus, you need to declare authorization rules both in the DSS projects, and in Sentry or Ranger.

For more information about the supported Hive security modes, see DSS and Hive

Impala

Details of security interaction between DSS and Impala are detailed in DSS and Impala
