How to set DEBUG log level for ResourceManager?
Quoting Setting debug log level for individual daemons:
Add
-Dhadoop.root.logger=DEBUGto something likeHADOOP_resourcemanager_optsinyarn-env.sh
etc/hadoop/hadoop-env.sh
search below line
export HADOOP_DAEMON_ROOT_LOGGER=INFO,RFA
for daemon, change INFO,RFA to DEBUG,RFAfor interactive process, there is another default setting above, change it
What worked for me is to add in yarn-env.sh
YARN_OPTS="$YARN_OPTS -Dhadoop.root.logger=${YARN_ROOT_LOGGER:-DEBUG,console}"YARN_OPTS="$YARN_OPTS -Dyarn.root.logger=${YARN_ROOT_LOGGER:-DEBUG,console}"
