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

  1. Inspect preceding logs: the status/reason warnings (3633) and 'commit error' stack traces identify the root cause per host.
  2. Verify FE connectivity and credentials for ALL configured FE hosts; fix auth or restore the down nodes.
  3. Check SelectDB FE/BE server logs for the COPY job failures (label conflicts, OOM, storage issues).
  4. Increase retry count/interval in the sink options if failures are transient (brief cluster restart).
  5. 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

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
