---------------------------------
Summary: Disable Iceberg table migration for unsupported source
file formats
Key: HIVE-25587
URL: https://issues.apache.org/jira/browse/HIVE-25587
Project: Hive
Issue Type: Improvement
Reporter: Marton Bod
Assignee: Marton Bod
Currently, we only support migrating ORC, Parquet and Avro tables to Iceberg.
However, there is no check in the code to fail early for other formats (e.g.
text, json, rcfile), which can lead to wasted effort at best, and leaving the
source table unusable at worst. Therefore, we should check the source format
early and shortcircuit for unsupported types.
