>             Project: Hive
>          Issue Type: Bug
>          Components: File Formats
>    Affects Versions: 0.13.1
>            Reporter: Frédéric TERRAZZONI
>            Assignee: Sergio Peña

> Tried write a map<string,string> column in a Parquet file. The table should contain
:
> {code}
> {"key3":"val3","key4":null}
> {"key3":"val3","key4":null}
> {"key1":null,"key2":"val2"}
> {"key3":"val3","key4":null}
> {"key3":"val3","key4":null}
> {code}
> ... and when you do a query like {code}SELECT * from mytable{code}
> We can see that the table is corrupted :
> {code}
> {"key3":"val3"}
> {"key4":"val3"}
> {"key3":"val2"}
> {"key4":"val3"}
> {"key1":"val3"}
> {code}
> I've not been able to read the Parquet file in our software afterwards, and consequently
I suspect it to be corrupted. 
> For those who are interested, I generated this Parquet table from an Avro file.
