Thanks Ryan for clarifying my questions!

>  a new representation for logical types. As of now this is not yet supported 
> in parquet-mr, thus there's no way to use parametrized UTC normalized 
> timestamp data types. When reading and writing Parquet files, besides 
> 'converted_type' parquet-mr should use the new 'logicalType' field in 
> SchemaElement to tell the current logical type annotation. To maintain 
> backward compatibility, the semantic of converted_type shouldn't change.
