             Summary: Unable to fetch column stats from decimal columns
                 Key: HIVE-7053
                 URL: https://issues.apache.org/jira/browse/HIVE-7053
             Project: Hive
          Issue Type: Bug
          Components: Statistics
    Affects Versions: 0.13.0
            Reporter: Xuefu Zhang


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   	 	 	 	 	 	 	 	 
{code}
