Daniel Becker has uploaded a new patch set (#15). ( http://gerrit.cloudera.org:8080/19322 )
Change subject: IMPALA-9551: Allow mixed complex types in select list ...................................................................... IMPALA-9551: Allow mixed complex types in select list Currently collections and structs are supported in the select list, also when they are nested (structs in structs and collections in collections), but mixing different kinds of complex types, i.e. having structs in collections or vice versa, is not supported. This patch adds support for mixed complex types in the select list. There is a limitation: zipping unnest for arrays that are within a struct is not supported, for example the following query: use functional_parquet; select unnest(struct_contains_nested_arr.arr) from collection_struct_mix; Testing: - Created a new test table, 'collection_struct_mix', that contains mixed complex types. - Added tests in mixed-collections-and-structs.test that test having mixed complex types in the select list. These tests are called from test_nested_types.py::TestMixedCollectionsAndStructsInSelectList. - Ran existing tests that test collections and structs in the select list; test queries that expected a failure in case of mixed complex types have been moved to mixed-collections-and-structs.test and now expect success.
