Description

Current we have SQLs to add row stats for partitioned/non_partitioned tables. For ex:

alter table analysis_data set tblproperties('numRows'='1001000000'); #non-partitioned
alter table partitioned_data set tblproperties ('numRows'='1030000'); #partitioned

We should have something similar for column stats too.
