> After HIVE-6701, column stats for decimal columns can be computed. However,
> when the stats are fetched, nothing is returned. The problem was originally
> reproducible using thrift API. With the patch in HIVE-7050, the problem can
> be also produced using "desc formatted table column".
> {code}
> hive> desc formatted dec i;
> OK
> # col_name data_type min
> max num_nulls distinct_count
> avg_col_len max_col_len num_trues
> num_falses comment
>
>
> i int 0 4
> 0 5 null
> null null null
> from deserializer
> hive> desc formatted dec d;
> OK
> # col_name data_type min
> max num_nulls distinct_count
> avg_col_len max_col_len num_trues
> num_falses comment
>
>
> d decimal(5,2) from deserializer
