Key: HIVE-16163
URL: https://issues.apache.org/jira/browse/HIVE-16163
Project: Hive
Issue Type: Bug
Reporter: Pengcheng Xiong
in HiveParser.g
L2145:
{code}
columnParenthesesList
@init { pushMsg("column parentheses list", state); }
@after { popMsg(state); }
: LPAREN columnNameList RPAREN
;
{code}
should be changed to
{code}

: LPAREN! columnNameList RPAREN!
;
{code}
However, we also need to refactor our code.
