Pull request overview
This PR updates the Flink tiering source to populate Fluss’ client.scanner.io.tmpdir from Flink runtime configuration when the Fluss config doesn’t explicitly set it, so remote-log downloads don’t default to /tmp in YARN deployments.
Changes:
- Set
CLIENT_SCANNER_IO_TMP_DIRinTieringSource#createReaderusingFlinkConnectorOptionsUtils.getClientScannerIoTmpDir(...). - Add static imports to support the above.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
