vinoyang commented on FLINK-9732:
---------------------------------

Hi [~Zentol] a little question, if the code "Job submission failed." at [this line|

https://github.com/apache/flink/blob/0cb7706dad74133652983a132d70ba4ded4aff9b/flink-runtime/src/main/java/org/apache/flink/runtime/rest/handler/job/JobSubmitHandler.java#L112

] is replaced with : 
{code:java}
exception.getMessage()
{code}
seems can get more information?

> Currently, if the job submission through the {{JobSubmitHandler}} fails the error message returned tot he client only says "Job submission failed.".
> As outlined in the discussion in this [PR|https://github.com/apache/flink/pull/6222] we should try to include more information about the actual failure cause.
> The proposed solution is to encode the cause for the failure in the {{Acknowledge}} that is returned by {{DispatcherGateway#submitJob}}.
> {code}
> public class AckOrException {
> 	// holds exception, could also be a series of nullable fields
> 	private final SuperEither<ExceptionA, ExceptionB, ExceptionC> exception; 
> 	...
> 	public void throwIfError() throws ExceptionA, ExceptionB, ExceptionC;
> }
> {code}
