             Summary: ASTNode rootNode is not maintained properly when changing child/parent relation
                 Key: HIVE-14719
                 URL: https://issues.apache.org/jira/browse/HIVE-14719
             Project: Hive
          Issue Type: Bug
            Reporter: Rui Li
            Assignee: Rui Li


When I run some query like:
{code}
set hive.cbo.enable=false;
select * from A where exists (select * from B where B.k1=A.k1 and B.k2=A.k2);
{code}
It gets error like:
{noformat}
FAILED: SemanticException Line 0:-1 Invalid table alias or column reference 'sq_1': (possible column names are: _table_or_col b) k2) sq_corr_1)) (tok, (. (tok_table_or_col sq_1) sq_corr_1))
{noformat}
