zhang-arvin opened a new pull request, #12662: URL: https://github.com/apache/gravitino/pull/12662
## What changes were proposed in this pull request? Add SQLSTATE `08S01` (Communication link failure) to the JDBC client pool retryable status codes, so that idle connections dropped by MySQL `wait_timeout` are automatically retried instead of failing with `CommunicationsException`. ## Why are the changes needed? Fixes #12589 The Iceberg JDBC catalog uses `JdbcClientPool` which does not retry on `08S01` by default. When MySQL `wait_timeout` closes an idle connection, the driver throws `CommunicationsException` with SQLSTATE `08S01`, causing catalog operations to fail. ## Does this PR introduce any user-facing change?
