------------------------------------

             Summary: Error messages from BashJavaUtils is eaten
                 Key: FLINK-18639
                 URL: https://issues.apache.org/jira/browse/FLINK-18639
             Project: Flink
          Issue Type: Bug
          Components: Deployment / Scripts
    Affects Versions: 1.11.0, 1.12.0
            Reporter: Xintong Song
            Assignee: Xintong Song
             Fix For: 1.12.0, 1.11.1


Shell scripts execute BashJavaUtils for generating memory related JVM parameters and dynamic configurations. When there's a problem in configuration that the memory sizes cannot be properly calculated, the script will not launch the Flink daemon and exit with non-zero code. In such cases, error messages from BashJavaUtils describing the reason of failure are missing, making it hard for users to understand what's wrong and how to fix the problem.
