> 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/.
