------------------------------------------
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.
