[~pxiong] Have you tested this with mysql which has tables pre-created (not auto created via datanucleus)? I think there might be issues because in those cases csid & partid being null will prevent data from getting inserted in db. 
I think let just simply revert HIVE-7876 before we figure out proper fix for this.

> We worked hard towards faster update stats for columns of a partition of a table previously 
> https://issues.apache.org/jira/browse/HIVE-7736

> https://issues.apache.org/jira/browse/HIVE-7876
> Although there is some improvement, it is only correct in the first run. There will be duplicate column stats later. Thanks to [~ekoifman] 's comments
