[jira] [Created] (FLINK-15504) Flink suppresses stdout/stderr during JobGraph generation from JAR

Maximilian Michels created FLINK-15504:
------------------------------------------

             Summary: Flink suppresses stdout/stderr during JobGraph generation from JAR
                 Key: FLINK-15504
                 URL: https://issues.apache.org/jira/browse/FLINK-15504
             Project: Flink
          Issue Type: Bug
          Components: Client / Job Submission
            Reporter: Maximilian Michels
            Assignee: Maximilian Michels


Flink uses the {@link org.apache.flink.client.program.OptimizerPlanEnvironment} which replaces stdout/stderr during job graph creation. This was intended only for previewing the plan, but other parts of Flink, e.g. the Rest API have started to use this code as well. 

It may be acceptable to suppress output during plan preview, but we should not suppress the output during execution, e.g. via the REST API.
