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

             Summary: Cannot start a taskmanger if using logback
                 Key: FLINK-15488
                 URL: https://issues.apache.org/jira/browse/FLINK-15488
             Project: Flink
          Issue Type: Bug
          Components: API / Core, Deployment / Scripts
    Affects Versions: 1.10.0
            Reporter: Dawid Wysakowicz
             Fix For: 1.10.0


When using logback it is not possible to start the taskmanager using {{taskamanger.sh}} scripts. The same problem (probably) occurs when using slf4j that logs into the console.

The problem is that when calculating memory configuration with {{BashJavaUtils}} class the result is returned through standard output. If something is logged into the console it may result in undefined behavior such as e.g.
{code}
Error: Could not find or load main class 13:51:23.961
{code}
