Hi Averell, The TM containers fetch the Flink binaries and config files form HDFS (or another DFS if configured) [1]. I think you should be able to change the log level by patching the logback configuration in HDFS, and kill all Flink containers on all hosts. If you are running an HA setup, your cluster should be running with the new logback configuration afterwards.
