Review comment:
Comma is missing after colStats. Does this still work fine, when you
generate the code ?

> 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.
