> Support SQL 2011 reserved keywords as identifiers in Flink HiveParser
> ----------------------------------------------------------------------
>
> Key: FLINK-35221
> URL: https://issues.apache.org/jira/browse/FLINK-35221
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / Hive
> Affects Versions: 1.20.0
> Reporter: Wencong Liu
> Priority: Major
> Labels: pull-request-available
>
> According to Hive user documentation[1], starting from version 0.13.0, Hive
> prohibits the use of reserved keywords as identifiers. Moreover, versions
> 2.1.0 and earlier allow using SQL11 reserved keywords as identifiers by
> setting {{hive.support.sql11.reserved.keywords=false}} in hive-site.xml. This
> compatibility feature facilitates jobs that utilize keywords as identifiers.
> HiveParser in Flink, relying on Hive version 2.3.9, lacks the option to treat
> SQL11 reserved keywords as identifiers. This poses a challenge for users
> migrating SQL from Hive 1.x to Flink SQL, as they might encounter scenarios
> where keywords are used as identifiers. Addressing this issue is necessary to
> support such cases.
