[jira] [Commented] (FLINK-8785) JobSubmitHandler does not handle JobSubmissionExceptions

["Chesnay Schepler (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-8785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16440751#comment-16440751 ] 

Chesnay Schepler commented on FLINK-8785:
-----------------------------------------

The {{ErrorResponseBody}} can accept a list of errors. I would suggest to pass in the the message of all exceptions in the trace.

For the response code we will have to stick to {{INTERNAL_SERVER_ERROR}} as we just can't differentiate between the errors right now.

> If the job submission, i.e. {{DispatcherGateway#submitJob}} fails with a {{JobSubmissionException}} the {{JobSubmissionHandler}} returns "Internal server error" instead of signaling the failed job submission.
> This can for example occur if the transmitted execution graph is faulty, as tested by the \{{JobSubmissionFailsITCase}}.
