### Apache Iceberg version 1.9.0 (latest release) ### Query engine Spark ### Please describe the bug 🐞 While reading changelog table with predicates on changelog metadata columns(such as _change_type), predicates could be pushed down through SparkScanBuilder::pushPredicates, but later expression evaluation would be failed due to table schema does not have changelog metadata columns. How to reproduce this issue? ``` CREATE TABLE t1 (c1 int, c2 string) USING iceberg; INSERT INTO t1 VALUES (1, 'a'), (2, 'b'); SELECT c1, _changelog_type FROM t1.changes WHERE _change_type = 'DELETE'; ``` ### Willingness to contribute - [x] I can contribute a fix for this bug independently - [ ] I would be willing to contribute a fix for this bug with guidance from the Iceberg community - [ ] I cannot contribute a fix for this bug at this time -- This is an automated message from the Apache Git Service.
