我在ubuntu13上将hadoopyarn（2.5.1）设置为单节点集群。当我运行start-dfs.sh时，它会给出以下输出，并且进程不会启动（我确认了usngjps和ps命令）。我的bashrc设置也复制到下面。关于我需要重新配置什么有什么想法吗？
bashrc补充：

export JAVA_HOME=/usr/lib/jvm/java-8-oracle
export HADOOP_INSTALL=/opt/hadoop/hadoop-2.5.1
export PATH=$PATH:$HADOOP_INSTALL/bin
export PATH=$PATH:$HADOOP_INSTALL/sbin
export HADOOP_MAPRED_HOME=$HADOOP_INSTALL
export HADOOP_COMMON_HOME=$HADOOP_INSTALL
export HADOOP_HDFS_HOME=$HADOOP_INSTALL
export YARN_HOME=$HADOOP_INSTALL
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_INSTALL/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_INSTALL/lib"

start-dfs.sh输出：

bin目录有hdfs文件，它的所有者是hduser（我以hduser的身份运行这个进程）。我的$hadoop\u安装设置指向hadoop目录（/opt/hadoop/hadoop-2.5.1）。我是否应该更改权限、配置或只是将目录从opt移到/usr/local？
更新：运行start-yarn.sh时，会收到以下消息：

localhost: Error: Could not find or load main class org.apache.hadoop.yarn.server.nodemanager.NodeManager

更新我把目录移到了/usr/local，但是得到了相同的警告消息。
更新我有resourcemanager按照jps命令运行。然而，当我尝试开始纺纱时，它失败了，出现了上面给出的错误。我可以访问端口8088上的resourcemanager ui。有什么想法吗？
