Error handling

Error handling

The Machine Learning transformation handles errors based on the type of issue that occurs and the response code that it receives from the REST API. You can review the response details in the Spark executor log.
The mapping fails when the following types of issues occur:
  • Connection issues when there is a connection timeout, the route cannot be found, or there is an unknown host.
  • Syntax issues in the URL.
  • SSL handshake issues such as certificate issues during SSL handshakes with the server.
The following table describes the action that occurs for each response code:
HTTP Status Code
Action
100 Continue
Row is skipped.
Partial requests are not permitted.
101,102,103 Informational, interim
Mapping fails.
3XX Redirection
Row is skipped.
Mapping fails if the redirected URL cannot be reached or the redirected URL returns a code that fails the mapping.
400 Bad request
