This patch reserves SQL:2016 reserved words, excluding: 1. Impala builtin function names. 2. Time unit words(year, month, etc.). 3. An exception list based on a discussion. Some test cases are modified to avoid these words. A impalad and catalogd startup option reserved_words_version is added. The words are reserved if the option is set to "3.0.0".
