In hadoop-yarn-project/hadoop-yarn/bin/yarn , you can find: YARN_OPTS="$YARN_OPTS -Dhadoop.root.logger=${YARN_ROOT_LOGGER:-INFO,console}" YARN_OPTS="$YARN_OPTS -Dyarn.root.logger=${YARN_ROOT_LOGGER:-INFO,console}"
Meaning you can override logger setting through YARN_ROOT_LOGGER environment variable.
