      Description

      If nodemanager is started under root (I know, I know). The following is displayed:

      /usr/lib/jvm/java-6-sun/bin/java -Dproc_nodemanager -Xmx1000m -jvm server -Dhadoop.log.dir=/var/log/yarn -Dyarn.log.dir=/var/log/yarn -Dhadoop.log.file=yarn-yarn-nodemanager-ahmed-laptop.log -Dyarn.log.file=yarn-yarn-nodemanager-ahmed-laptop.log -Dyarn.home.dir=/usr/lib/hadoop -Dhadoop.root.logger=INFO,DRFA -Dyarn.root.logger=INFO,DRFA -Djava.library.path=/usr/lib/hadoop/lib/native -classpath /etc/hadoop/conf:/etc/hadoop/conf:/etc/hadoop/conf:/usr/lib/hadoop/share/hadoop/common/*::/usr/lib/hadoop/*:/usr/lib/hadoop/lib/*:/usr/lib/hadoop/:/usr/lib/hadoop/share/hadoop/hdfs/*:/usr/lib/hadoop/share/hadoop/mapreduce/*:/share/hadoop/mapreduce/*:/usr/lib/hadoop/share/hadoop/mapreduce/*:/usr/lib/hadoop/share/hadoop/mapreduce/lib/*:/etc/hadoop/conf/nm-config/log4j.properties org.apache.hadoop.yarn.server.nodemanager.NodeManager
      Unrecognized option: -jvm
      Could not create the Java virtual machine.
      

      The culprit is this bit of code that looks suspiciously like what used to be in bin/hdfs in support of jsvc launch:

      elif [ "$COMMAND" = "nodemanager" ] ; then
        CLASSPATH=${CLASSPATH}:$YARN_CONF_DIR/nm-config/log4j.properties
        CLASS='org.apache.hadoop.yarn.server.nodemanager.NodeManager'
        if [[ $EUID -eq 0 ]]; then
          YARN_OPTS="$YARN_OPTS -jvm server $YARN_NODEMANAGER_OPTS"
        else
          YARN_OPTS="$YARN_OPTS -server $YARN_NODEMANAGER_OPTS"
        fi
