IMPALA-11840: Error with joining unnest with views
Queries fail when an array is taken from a view, unnested in another
view and then the result 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_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.
