We made a mistake in https://github.com/apache/spark/pull/16944 . In `HiveMetastoreCatalog#inferIfNeeded` we infer the data schema, merge with full schema, and return the new full schema. At caller side we treat the full schema as data schema and set it to `HadoopFsRelation`. This doesn't cause any problem because both parquet and orc can work with a wrong data schema that has extra columns, but it's better to fix this mistake. N/A Author: Wenchen Fan <wenchen@databricks.com> Closes #19615 from cloud-fan/infer. (cherry picked from commit 4d9ebf3835dde1abbf9cff29a55675d9f4227620) Signed-off-by: Wenchen Fan <wenchen@databricks.com>
