If you have already updated the log4j.properties, and it still could not work, then Isuggest to log in the Yarn NodeManager machine and check the log4j.propertiesin the container workdir is correct. Also you could have a look at the java dynamicoptions are correctly set.I think it should work if the log4j.properties and java dynamic options are set correctly.BTW, could you share the new yarn logs?Best,YangDiwakar Jha <[hidden email]> 于2020年11月2日周一 下午4:32写道：Hi Yang,Thank you so much for taking a look at the log files. I changed my log4j.properties. Below is the actual file that I got from EMR 6.1.0 distribution of flink 1.11. I observed that it is different from Flink 1.11 that i downloaded so i changed it. Still I didn't see any logs.Actual

The JobManager and TaskManagerjava processes have been started with correct dynamic options, especially for the logging.Could you share the content of $FLINK_HOME/conf/log4j.properties? I think there's something wrong with thelog4j config file. For example, it is a log4j1 format. But we are using log4j2 in Flink 1.11.Best,YangDiwakar Jha <[hidden email]> 于2020年11月2日周一 上午1:57写道：HiI'm running Flink 1.11 on EMR 6.1.0.
