## AI overview

Trino 470 deprecated its legacy Hadoop-based file system support, which will be removed in a future release. The article explains Trino's move toward custom file system implementations for cloud storage and describes the migration path for users, including catalog-level file system configuration and warnings for deprecated properties.

## Source excerpt

What a long journey it has been! From the start Trino supported querying Hive data and used libraries from the Hive and Hadoop ecosystem. With the release of Trino 470 we mark another milestone to more features and better performance for data lake and lakehouse querying with Trino. We deprecated the legacy file system support, and will permanently remove them in an upcoming release.
