Impala does not support super user configuration for the observability user for Apache Ranger-enabled cluster
The observability user requires full privileges on the Observability cluster. Required services such as Kafka, HDFS, HBase, and Hive support super user setup by specifying the ranger.plugin.[service].super.users property to observability. However, this super user setup is not supported for Impala.
Manually add a new user named observability in Apache Ranger and assign full privileges.

  • For information on granting user access using Apache Ranger, see Impala Authorization in Cloudera Data Warehouse Runtime for Cloudera on premises documentation.
