Get Error URL failed. {}
Error message
Get Error URL failed. {} What it means
When a StarRocks stream load fails, the connector attempts to fetch the ErrorURL returned by StarRocks to include detailed error info in the thrown exception. This warning is logged when the HTTP GET of that ErrorURL itself fails (IOException), so only the load result JSON is included in the StarRocksConnectorException.

Solutions
- Check network connectivity from the SeaTunnel node to the StarRocks BE HTTP port returned in the ErrorURL host
- Inspect the stream load response JSON already logged ('StreamLoad response') for the real failure reason
- Verify firewalld/security-group rules allow HTTP access to all BE nodes
- Check the exception's caused-by for the underlying IOException (timeout vs refused)
Defensive patterns
Strategy: try-catch
Validate before calling
// verify BE http reachability before the job curl -s http://<be-host>:<http_port>/api/show_meta_info
Try / catch
try {
throw new StarRocksConnectorException(errorBuilder + errorUrlBody);
} catch (StarRocksConnectorException e) {
// inspect loadResult JSON in message even if ErrorURL fetch failed
LOG.error("stream load failed; parse embedded response", e);
} Prevention
- Open firewall access from SeaTunnel nodes to all BE http ports
- Monitor the logged 'StreamLoad response' as the authoritative error source
- Keep job timeout larger than BE error-URL retention
When it happens
Trigger: A stream load returns a non-success response containing an ErrorURL, and httpHelper.doHttpGet throws IOException (network failure, BE unreachable on its http port, timeout, wrong http_port config).
Common situations: StarRocks BE frontend port (webserver_num_workers/http_port 8030/8040) blocked by firewall or security group; BE node down; DNS resolution failure; load failed and the error URL expired before fetch.
