Peter Vary commented on HIVE-14146:
-----------------------------------
[~aihuaxu] I have checked those lines you mentioned.
The difference between the new and the original lines is that in the new
version there are whitespaces at the end of every cell to make the width of the
last column the same as every other column. The new line was there before the
patch.
> Column comments with "\n" character "corrupts" table metadata
