## Problem - paimon 1.1.1 JDBC catalog keeps long-lived JDBC connections in `JdbcClientPool` - borrowed connections are reused without validity checks - after MySQL `wait_timeout`, read paths can fail with stale connection errors such as `CJCommunicationsException` / `Broken pipe` ## Fix - detect stale JDBC connection failures in `PaimonExternalCatalog` for JDBC catalogs - reset the catalog to uninitialized, rebuild the underlying Paimon catalog, and retry read operations once - keep retry scope on read paths only to avoid replaying mutating DDL operations - clear `metadataOps` and `catalog` references during close to prevent stale objects from being reused ## Tests - added `PaimonJdbcCatalogReconnectTest` - verified the targeted FE UT passed: `Tests run: 3, Failures: 0, Errors: 0, Skipped: 0` -- This is an automated message from the Apache Git Service.
