commit failed, retry again
Error message
commit failed, retry again
What it means
CopySQLUtil.copyFileToDatabase() retries the commit across SelectDB FE hosts until one returns 307 and a successful load result; on every non-successful iteration it logs 'commit failed, retry again' (log.warn/info) and loops. If all attempts fail, a SelectDBConnectorException is thrown afterwards.
Solutions
- Inspect preceding logs: the status/reason warnings (3633) and 'commit error' stack traces identify the root cause per host.
- Verify FE connectivity and credentials for ALL configured FE hosts; fix auth or restore the down nodes.
- Check SelectDB FE/BE server logs for the COPY job failures (label conflicts, OOM, storage issues).
- Increase retry count/interval in the sink options if failures are transient (brief cluster restart).
- Test the COPY statement manually with curl to confirm the cluster accepts loads at all.
Example fix
// before
} else {
log.warn("commit failed, retry again");
}
// after (operator-side validation before running the sink)
# ensure at least one FE is healthy before the job
curl -u user:pass http://fe-host:8030/api/health
# then rerun; persistent failure -> check FE/BE logs Defensive patterns
Strategy: retry
Validate before calling
// pre-check cluster health and auth before running the sink curl -u user:pass http://fe-host:8030/api/health # and confirm COPY permissions for the user/cluster
Try / catch
try {
copySqlUtil.copyFileToDatabase(...);
} catch (SelectDBConnectorException e) {
// all retries exhausted: inspect preceding 'commit failed, retry again'
// and status warnings; only retry at job level for transient causes
} Prevention
- Ensure at least one healthy FE before starting loads
- Tune retry count/interval for expected transient downtime
- Watch for COPY label conflicts and use unique labels per load
- Confirm user quotas and cluster capacity can accept the load size
When it happens
Trigger: Every commit attempt in the retry loop fails — statuses other than 307, connection errors caught earlier (log.error('commit error : ', e) → continue), or an error body in the redirect response — for the full number of configured retries.
Common situations: All SelectDB FE nodes unreachable or rejecting credentials; persistent 307 loop where the final ingest endpoint keeps failing; network partition between SeaTunnel worker and SelectDB cluster; file too large or COPY label conflicts returning errors on each try; cluster capacity/suspend issues.
Understand the failure class
Background: 'Something went wrong' / 'Request failed (500)' / 'HTTP error! status: 404' — what failed HTTP requests actually mean and how to find the real cause — this error's family across 28 libraries.
