--------------------------------------
Summary: Make UnsuccessfulExecutionException part of the
JobClient.getJobExecutionResult() contract.
Key: FLINK-20020
URL: https://issues.apache.org/jira/browse/FLINK-20020
Project: Flink
Issue Type: Improvement
Components: Client / Job Submission
Affects Versions: 1.12.0
Reporter: Kostas Kloudas
Assignee: Kostas Kloudas
Currently, different implementations of the {{JobClient}} throw different
exceptions. The {{ClusterClientJobClientAdapter}} wraps the exception from the
{{JobResult.toJobExecutionResult()}} into a {{ProgramInvocationException}}, the
{{MiniClusterJobClient}} simply wraps it in a {{CompletionException}} and the
{{EmbeddedJobClient}} wraps it into an {{UnsuccessfulExecutionException}}.
With this issue I would like to propose making the exception uniform and part
of the contract and as a candidate I would propose the behaviour of the
{{EmbeddedJobClient}} which throws an {{UnsuccessfulExecutionException}}. The
reason is that this exception also includes the status of the application.
