Subject [jira] [Commented] (FLINK-15488) Cannot start a taskmanger if using logback
Date Tue, 07 Jan 2020 09:56:00 GMT

Yangze Guo commented on FLINK-15488:
------------------------------------

Disable logging makes sense to me. Actually, it's a bit odd to allow logging in this utility
class.

> 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}
