["Tim (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-9281?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16461564#comment-16461564 ] 

Tim commented on FLINK-9281:
----------------------------

Update:   Looks like this works with logback v1.1.3, but does not work with version 1.3.0-alpha4.     

Here's what I have in my $FLINK_DIR/lib folder:
 # logback-classic-1.1.3.jar
 # logback-core-1.1.3.jar
 # log4j-over-slf4j-1.7.7.jar

> I am trying to get Flink to work with Logback instead of Log4J.   However, it is not working. 
> My setup is as follows the advice on this page: https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/best_practices.html#use-logback-when-running-flink-on-a-cluster
>  * Flink v1.4.2 running a stand-alone cluster. 
>  * Started JobManager as a foreground process (bin/jobmanager.sh start-foreground cluster).  I updated bin/flink-console.sh to reference logback.xml via -Dlogback.configurationFile=file:/path/to/logfile.
>  * Removed log4j jars under libs/  (log4j-1.2.xx.jar and sfl4j-log4j12-xxx.jar)
>  * Added logback jars under libs/   (logback-classic, logback-core, log4j-over-slf4j.jar) 
> However, I am not getting any file created.   Also, as a dumb test I referenced a non-existent logback.xml file (changed path to a non-existent folder) just to see if any errors appear on stdout, but nothing.
> Thanks
