Description

running "sudo HADOOP_ROOT/bin/yarn-daemon.sh start nodemanager" I get "unknown -jvm option" (jdk version 1.6.0.26). The problem seems to be with line 204 in yarn:

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

using -server seems to solve the problem for me.

I tested using build 929 from https://builds.apache.org/view/G-L/view/Hadoop/job/Hadoop-Mapreduce-trunk/.
