The details of the step failure. The service attempts to detect the root cause for many common failures.

See: newFailureDetails smart constructor.

Create a value of FailureDetails with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:logFile:FailureDetails', failureDetails_logFile - The path to the log file where the step failure root cause was originally recorded.

$sel:reason:FailureDetails', failureDetails_reason - The reason for the step failure. In the case where the service cannot successfully determine the root cause of the failure, it returns "Unknown Error" as a reason.

$sel:message:FailureDetails', failureDetails_message - The descriptive message including the error the Amazon EMR service has identified as the cause of step failure. This is text from an error log that describes the root cause of the failure.
