Apache Hive Changes in CDP
You need to know where your tables are located and the property changes that the upgrade process makes. You need to perform some post-migration tasks before using Hive tables and handle semantic changes.
Understanding Apache Hive 3 major design features, such as default ACID transaction processing, can help you use Hive to address the growing needs of enterprise data warehouse systems.
If you are expediting the Hive upgrade process and modified the upgrade process to skip materializing every table in the metastore, you need to modify the Hive Strict Metastore Migration (HSMM) process by running the Hive Upgrade Check tool and provided scripts. Scripts are not included to address legacy Kudu storage handler classes.
