HIVE_SUPPORT_SQL11_RESERVED_KEYWORDS

To simplify the parser logic and largely reduce the size of generated parser code, the HIVE_SUPPORT_SQL11_RESERVED_KEYWORDS configuration has been removed.

Before Upgrade to CDP

HIVE-14872 removed support for this configuration in Hive 2.3. HIVE_SUPPORT_SQL11_RESERVED_KEYWORDS configuration offered backward compatibility. Reserved keywords were used as identifiers in the previous releases.

After Upgrade to CDP

CDP releases support later versions of Hive that do not support the configuration.
