Ashutosh Chauhan commented on HIVE-7944:
----------------------------------------

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

> 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
