-----------------------------
> Remove V2 file write guards, unify schema validation, and support custom
> partition locations
> --------------------------------------------------------------------------------------------
>
> Key: SPARK-56172
> URL: https://issues.apache.org/jira/browse/SPARK-56172
> Project: Spark
> Issue Type: Sub-task
> Reporter: Yang Jie
> Priority: Major
>
> Remove guards that block `FileDataSourceV2` from the V2 write path:
> # `DataSourceV2Utils.getTableProvider` filter controlled by feature flag,
> enabling catalog-managed tables to use V2.
> # `FileTable.schema` removes over-aggressive column name duplication check
> (moved to `FileWrite.validateInputs` for write path only) and skips
> `supportsDataType` for partition columns on the read path.
> # Add `customPartitionLocations` support:
> `FileTable.getCustomPartitionLocations` mirrors V1's
> `InsertIntoHadoopFsRelationCommand`, comparing catalog partition locations
> against default paths. Plumb through all format Write/Table classes.
