CREATE TABLE agg1

col0 INT,
col1 STRING,
col2 DOUBLE
);
explain SELECT single_use_subq11.a1 AS a1,
single_use_subq11.a2 AS a2
FROM (SELECT Sum(agg1.col2) AS a1
FROM agg1
GROUP BY agg1.col0) single_use_subq12
JOIN (SELECT alias.a2 AS a0,
alias.a1 AS a1,
alias.a1 AS a2
FROM (SELECT agg1.col1 AS a0,
'42' AS a1,
agg1.col0 AS a2

GROUP BY alias.a2,

ON ( single_use_subq11.a0 = single_use_subq11.a0 );

Gets the following error:
FAILED: SemanticException [Error 10007]: Ambiguous column reference a2
Looks like this query had been working in 0.12 but starting failing with this
error in 0.13
