Are you setting HADOOP_CONF_DIR in hadoop-env.sh? Do you have YARN_HOME set in hadoop-env.sh? Is your yarn-env.sh just the standard one from ./hadoop-mapreduce-project/hadoop-yarn/conf/yarn-env.sh?

I am able to run the below command successfully from the terminal, but the yarn-daemons.sh (plural) command exits with the above error. >> ssh praveen-laptop cd >> /home/praveensripati/Installations/hadoop-0.23.0/bin/.. ; >> /home/praveensripati/Installations/hadoop-0.23.0/bin/yarn-daemon.sh --config >> /home/praveensripati/Installations/hadoop-0.23.0/conf start nodemanager I looked at the code and could not figure it out. Did I miss anything or is there a bug in the code? Regards, Praveen
