Lefty Leverenz commented on HIVE-17540:
---------------------------------------
Doc note: This removes the non-reserved keyword PRETTY so the DDL doc needs to
be updated for release 3.0.0. It would also be nice to document the removed
syntax (with release information) in the Describe section of the DDL doc.
* [DDL -- Non-reserved Keywords |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-Non-reservedKeywords]
* [DDL -- Describe |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-Describe]
Added a TODOC3.0 label. (Please add your own TODOC labels and doc notes from
now on. I no longer monitor Hive email for doc issues.)

> I've bumped into "describe pretty" feature...which was probably a usefull
> thing when it was introduced....but I haven't seen it documented anywhere ...

> this feature makes it possible to render column comments more nicely...
> I think beeline is already able to address formatting issues like this at a
> much wider scale; so it might be ok to remove the 'describe pretty'
> support...or at least I think it would be better to put efforts into
> displaying things on beeline more nicely
