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.
