TisonKun created FLINK-13332:
--------------------------------

             Summary: PackagedProgram#isUsingInteractiveMode implemented error prone
                 Key: FLINK-13332
                 URL: https://issues.apache.org/jira/browse/FLINK-13332
             Project: Flink
          Issue Type: Bug
          Components: Command Line Client
    Affects Versions: 1.10.0
            Reporter: TisonKun


Currently, {{PackagedProgram#isUsingInteractiveMode}} implemented as

{code:java}
public boolean isUsingInteractiveMode() {
    return this.program == null;
}
{code}

is hacky and a better implementation would be

{code:java}
public boolean isUsingInteractiveMode() {
    return hasMainMethod(mainClass);
}
{code}
