Melmoth created FLINK-4724:
------------------------------

             Summary: When executed in YARN wrong log4j & logback configuration file is used
                 Key: FLINK-4724
                 URL: https://issues.apache.org/jira/browse/FLINK-4724
             Project: Flink
          Issue Type: Bug
    Affects Versions: 1.1.2
            Reporter: Melmoth


I start Flink by executing bin/yarn-session.sh.
To change the log levels of the Taskmanager, I have to edit conf/log4j.properties instead of conf/log4j-yarn-session.properties.
I have not found any documentation on this, but this seems like a bug to me.

The Taskmanager logs indicate that non-yarn configuration files are added to the classpath:

2016-10-01 13:22:19,267 INFO  org.apache.flink.yarn.YarnTaskManagerRunner                   -  Classpath: *logback.xml:log4j.properties*:lib/flink-dist_2.11-1.1.2.jar:lib/slf4j-log4j12-1.7.7.jar....

Or is there another usecase of the yarn logger config files?
