+## Open topics
+
+Iceberg integration
+
+The easiest way of integrating Iceberg in TDP is to use Hive 4. Therefore, Hadoop 3.3.6 and Tez 0.10.3 are required. Zookeeper version has been changed to 3.8 for Hadoop. Hive 4 is being tested at the moment with Ranger 2.5. With all these components, Iceberg has been deployed in a cluster where it is currently being tested. The following operations have been successfully performed: created a table in Iceberg format, renamed the table, renamed a column, added a line and more. All the metadata of the tables and transformations is available. However some operations in Hive do not work and are currently being investigated.
