partitions.

> The code here expects a blank line in "# Partition Information" section after "# col_name"
line, in "desc formatted tablename" output, which does exist in Hive 2, CLI mode:
> {code:java}
> # Partition Information
> # col_name data_type comment
> pt string
> {code}
>  
> But in Hive3, Beeline client, it outputs:
> {code:java}
> | # Partition Information       | NULL                                              
| NULL                  |
> | # col_name                    | data_type                                         
| comment               |
> | pt                            | string                                            
|                       |
> {code}
>  
> The blank line is gone, which makes folloing line fails. 
> {code:java}
