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

  1. Check network connectivity from the SeaTunnel node to the StarRocks BE HTTP port returned in the ErrorURL host
  2. Inspect the stream load response JSON already logged ('StreamLoad response') for the real failure reason
  3. Verify firewalld/security-group rules allow HTTP access to all BE nodes
  4. 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

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.
