### Purpose fix #10402 - Hive does not cast SARG literals to the column type, so `convertJavaObject` rounds or nulls a DECIMAL literal (`1.005`, `1000` for `DECIMAL(5, 2)`) and wraps an out-of-range TINYINT/SMALLINT/INT literal (with `hive.cbo.enable=false`). - The altered predicate drives stats-based file skipping, so files with matching rows are dropped and Hive's residual filter cannot recover them. - `toLiteral()` now throws `UnsupportedOperationException` when the converted literal differs from the Hive value, so `convert()` leaves that conjunct to Hive (same fallback as #9448). This only reduces pushdown; no query newly fails. ### Tests - `SearchArgumentToPredicateConverterTest`: new cases for decimal precision/scale overflow, integer overflow, and representable controls. The three overflow cases fail without the fix. - `HiveReadITCaseBase#testPredicatePushDownWithLiteralsNotRepresentableInColumnType` (MR and Tez): one file per row; returns `[]` for `c < 1000` without the fix. - `mvn -pl paimon-hive/paimon-hive-connector-common clean install` (JDK 11): 202 tests, 0 failures. -- This is an automated message from the Apache Git Service.
