Change subject: IMPALA-11840: Error with joining unnest with views ...................................................................... IMPALA-11840: Error with joining unnest with views Queries fail in the following situation involving collections and views: 1. A view returns an array 2. A second view unnests the array returned from the first view 3. the unnested view is queried in an outer query For example: use functional_parquet; with sub as ( select id, arr1.item unnested_arr from complextypes_arrays_only_view, complextypes_arrays_only_view.int_array arr1) select id, unnested_arr from sub; ERROR: IllegalStateException: null The problem is that in CollectionTableRef.analyze(), if - there is a source view and - the collection ref is within a WITH clause and - it is not in the select list then 'desc_' is not set, but it has to be set in order for TableRef.analyzeJoin() to succeed. This commit solves the problem by assigning a value to 'desc_' also in the above case. Testing: - Added regression tests in nested-types-runtime.test.
