Subject [jira] [Commented] (HIVE-12707) ParseException for column name 'INTERVAL', even set hive.support.sql11.reserved.keywords = false

Pengcheng Xiong commented on HIVE-12707:
----------------------------------------

[~rajsaha], here is the story with timeline: Hive 0.14 was released based on commits on Wed
Nov 12 20:35:15 2014 (Since INTERVAL was not introduced yet, you are free to use it as identifier).
The flag "hive.support.sql11.reserved.keywords" was introduced on Tue Mar 10 22:00:41 2015.
(Since INTERVAL was not introduced yet, you are free to use it as identifier whether you set
the flag or not). "INTERVAL" was introduced on Thu Mar 19 19:05:28 2015 (see HIVE-9792 : Support
interval type in expressions/predicates ), and they reserved it.... Sounds like the people
who checked in HIVE-9792 did not consider the backward compatibility of "interval". So, if
it really makes trouble for you, i can add it back to the list. But as you know, we are planning
to deprecate the flag in the next release or two.
