xylaaaaa opened a new pull request, #61923: URL: https://github.com/apache/doris/pull/61923
## Summary - Cherry-pick #61513 onto `branch-4.1` - Propagate JDBC driver metadata to BE for Paimon JDBC system-table JNI scans - Register the JDBC driver in a DriverManager-visible classloader before Paimon table initialization - Extend the regression case to cover all supported Paimon JDBC system tables ## Root Cause Paimon JDBC system-table queries that ran through the BE JNI scanner could fail to initialize the PostgreSQL JDBC driver and returned `No suitable driver found`. ## Backport Note - Resolved the cherry-pick conflict in `be/src/format/table/paimon_jni_reader.cpp` by keeping the `branch-4.1` JniReader construction path and porting the scan-level `paimon_options` fallback logic ## Validation - `git diff --check origin/branch-4.1..HEAD` - Not run: FE/BE unit tests or regression tests in this worktree -- This is an automated message from the Apache Git Service.
