    • Test DB connection tool supports Oracle RAC

  • SDX Enhancements

    • Ranger authorization for Hive table creation now supports new resources “storage-type” and “storage-url” and one permission “RW Storage. When doAs = false superuser “hive” would be the user creating the tables in the specified storage and this results in table creation to get authorized for user hive and not for the original user who issued the ‘create/ alter table’ command.

    • Ranger Usersync services will update Ranger when users and groups have been deleted from the sync source (UNIX, LDAP, AD or PAM). This ensures that users and groups – and their associated access permissions – do not remain in Ranger when they are deleted from sync source.

    • CM Configurable Maximum Retention Days attribute for Ranger audits. Now users can update the solr document expiry ranger.audit.solr.config.ttl and ranger.audit.solr.config.delete.trigger parameters from CM in Ranger configurations and refresh configurations to get the Solr collection for Ranger audits updated with ttl and delete trigger.

    • Kudu integration with Hive Metastore can now be configured via Cloudera Manager

    • Kudu supports multi-row transactions for INSERT and INSERT_IGNORE operations (TP)

  • Streaming Enhancements

    • The Kafka service can now be configured to automatically publish topic metadata to Apache Atlas. Kafka topics will show up in Atlas as individual entities as well as in Data Lineage graphs.

    • Streams Messaging Manager (SMM) can now be configured to use an external Prometheus metric store instead of Cloudera Manager’s internal metric store. This improves SMM scalability for large Kafka deployments with a high number of topics, partitions, consumers, and producers.

    • Streams Replication Manager now supports storing all sensitive data in a secure manner.
