> HS2ColumnarResultSet::AddRows(const QueryResultSet* other ... ) is not prepared for handling complex types: https://github.com/apache/impala/blob/1d16367afb1e520bae5992c1e6c92b4fb41d2655/be/src/service/query-result-set.cc#L412
> A debug build will hit the DCHECK, while a release build will crash a bit later. This didn't come up during testing as impala-shell doens't set impala.resultset.cache.size
