[Apache Wiki]

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change 
notification.

The "Hive/LanguageManual/Transform" page has been changed by HenryLudemann.
The comment on this change is: The row format appears to have to come after the 
'AS'. Not doing so results in a "...cannot recognize input 'as' in record 
reader specification..." error..
