Description

IMPALA-9495 adds support for struct types in SELECT lists but only with codegen turned off. We should remove this restriction either by implementing codegen for struct types or calling interpreted code from codegen code to handle structs. This latter option is still better than turning off codegen completely because other parts of the query that do not handle structs could benefit from codegen.
