>             Project: IMPALA
>          Issue Type: Improvement
>          Components: Frontend
>    Affects Versions: Impala 4.1.0

> IMPALA-9496 added support for providing structs in the select list for Parquet files as well. However, when a struct member is used in a WHERE filter and the struct is also present in the select list then there would be a tuple/slot ID mismatch during the planning. The reason is that in one place the tuple/slot ID of the predicate is used through the struct while in other occasion the general ID is used.
> To reproduce you have to remove the corresponding exit condition from HdfsScanNode.addDictionaryFilter(), rebuild, and run the following query:
> {code:java}
> select id, str, alltypes
> from complextypes_structs
> where alltypes.b = true; {code}
