> Hive supports "alter view" on setting property, add/drop partition etc but not "as".
> If you want to change "as" part, you have to drop view, recreate it and backfill partition
etc. pretty painful.
> It will be nice to support this. The reference is mysql syntax http://dev.mysql.com/doc/refman/5.0/en/alter-view.html
