Preparing tables for migration
You download the Hive Upgrade Check tool and use it to identify problems in unmigrated tables. These problems can cause upgrade failure. It saves time to fix the problems and avoid failure. The tool provides help for fixing those problems before migrating the tables to CDP.
You use the Hive Upgrade Check community tool to help you identify tables that have
problems affecting migration. You resolve problems revealed by the Hive Upgrade
Check tool to clean up the Hive Metastore before migration. If you do not want to
use the Hive Upgrade Check tool, you need to perform the tasks described in the
following subtopics to migrate Hive data to CDP:
- Check SERDE Definitions and Availability
- Handle Missing Table or Partition Locations
- Manage Table Location Mapping
- Make Tables SparkSQL Compatible
