Prasad Chakka commented on HIVE-571:
------------------------------------
if we can support changing of the column type in other alter table statements
(REPLACE COLUMNS), why not support it here? also why not exactly support the
mysql syntax
{code}
CHANGE [COLUMN] old_col_name new_col_name column_definition
[FIRST|AFTER col_name]
{code}
atleast we should support changing the comment.
> add ability to rename a column.

> be cumbersome if the table has lots of columns.
