Answer 1

I modified the script $HADOOP_HOME/sbin/yarn-daemon.sh , ie: removed nohup

from :

nohup nice -n $YARN_NICENESS "$HADOOP_YARN_HOME"/bin/yarn --config $YARN_CONF_DIR $command "$@" > "$log" 2>&1 < /dev/null &

to

nice -n $YARN_NICENESS "$HADOOP_YARN_HOME"/bin/yarn --config $YARN_CONF_DIR $command "$@" > "$log" 2>&1 < /dev/null &

and now i am able to start resourcemanager
