> For the current implementation with VectorizedParquetRecordReader, only following definition
for map type is supported:
> {code}
> repeated group map (MAP_KEY_VALUE) {
>     required binary key (UTF8); optional binary value (UTF8);}
> }
> {code}
> The implementation should support multiple level definition like:
> {code}
> optional group m1 (MAP) {
>     repeated group map (MAP_KEY_VALUE)
>         {required binary key (UTF8); optional binary value (UTF8);}
> }
> {code}
