Subject [jira] [Created] (HIVE-13147) COLUMN_STATS_ACCURATE is not accurate
Date Wed, 24 Feb 2016 18:32:18 GMT
Romain Rigaux created HIVE-13147:
------------------------------------

             Summary: COLUMN_STATS_ACCURATE is not accurate
                 Key: HIVE-13147
                 URL: https://issues.apache.org/jira/browse/HIVE-13147
             Project: Hive
          Issue Type: Bug
    Affects Versions: 1.2.0
            Reporter: Romain Rigaux


Often we see on a described table:
{code}
Table Parameters:	NULL	NULL
18		COLUMN_STATS_ACCURATE	true                
19		numFiles            	1                   
20		numRows             	0                   
21		rawDataSize         	0                   
22		totalSize           	46069               
23		transient_lastDdlTime	1448930216          
{code}

Notice
{code}
20		numRows             	0                   
21		rawDataSize         	0       
{code}
are wrong.

After doing an analyze we get:
{code}
Table Parameters:	NULL	NULL
18		COLUMN_STATS_ACCURATE	true                
19		numFiles            	1                   
20		numRows             	823                 
21		rawDataSize         	45246               
22		totalSize           	46069               
23		transient_lastDdlTime	1456338426 
{code}
