             Summary: Add optional fields to enable returning filemetadata for tables and partitions
                 Key: HIVE-25281
                 URL: https://issues.apache.org/jira/browse/HIVE-25281
             Project: Hive
          Issue Type: Improvement
            Reporter: Vihang Karajgaonkar
            Assignee: Vihang Karajgaonkar


The hive_metastore.thrift interface defines the fields for Table and Partition objects. Certain SQL engines like Impala use Table and Partition from the HMS and then augment it to include additional metadata useful for the engine itself e.g file metadata. It would be good to add support for such fields in the thrift definition itself. These fields currently will be optional fields so that HMS itself doesn't really need to support it for now, but this can be supported in future depending on which SQL engine is talking to HMS.
