As a Dataiku user who relies on Hive and HDFS, you’ll want to ensure your transition to the new platform is smooth and that you maintain access to your datasets with minimal disruption. Here are key questions to ask your platform migration team to protect your data assets and maintain productivity during and after the migration.

Data Preservation and Access

Dataset Continuity

1. Will all my existing HDFS datasets be migrated to the new storage system ?
2. Ask for confirmation that all paths and directories will be preserved or properly mapped
3. Request details on any naming convention changes that might affect your workflows

2. How will historical data in Hive tables be handled?

• Will the complete history be migrated or only data after a certain date?
• Will table schemas remain identical or require modifications?

3. Will my custom Hive partitioning schemes be preserved in the new environment?

. If not, what changes will I need to make to my queries and workflows?
