Ashutosh Chauhan commented on HIVE-701:
---------------------------------------
After this commit, it seems like grammar has became far more ambiguous. It was
ambiguous even before, but judging from number of warnings during generation of
parser it seems like it has become much worse.
[~sxyuan] / [~kevinwilfong] is there any plan to address those warnings?
> lots of reserved keywords in hive

> There is a problem if we want to use some reserved keywords:
> for example, creating a function of name left/right ? left/right is already a
> reserved keyword.
> The other way around should also be possible - if we want to add a 'show
> tables status' and some applications already use status as a column name,
> they should not break
