IMPALA-13494: Calcite planner group_concat with distinct failing
The following query is failing.
select sum(len_orderkey), sum(len_comment)
from (
select
length(group_concat(distinct cast(l_orderkey as string))) len_orderkey,
length(group_concat(distinct(l_comment))) len_comment
from tpch.lineitem
group by l_comment
) v
There is code where in AggregationFunction for group_concat that calls
to ignore an implicit cast. The 'isImplicitCast_' member is being used
directly in this function, but the variable is overridden in the
isImplicitCast method for the Calcite planner. A small change was needed
to call the isImplicitCast() function rather than use the member variable.
