Ashutosh Chauhan commented on HIVE-2415:
----------------------------------------

Won't doing validation in parser will result in two network calls, first to 
fetch the current column info and then update. I am wondering if it will be 
better to do one call to metastore which will first validate the columns and 
then do the update.

> disallow partition column names when doing replace columns
