原因：
使用root账号启动服务，但没预先定义
解决方法：
* 该步骤需要在每台机都执行，也可以先在其中一台机修改，再用scp同步给其它机
1.修改start-dfs.sh和stop-dfs.sh
cd /home/hadoop/sbin vim start-dfs.sh vim stop-dfs.sh
HDFS_ZKFC_USER=root HDFS_JOURNALNODE_USER=root HDFS_NAMENODE_USER=root HDFS_SECONDARYNAMENODE_USER=root HDFS_DatanODE_USER=root HDFS_DatanODE_SECURE_USER=root #HADOOP_SECURE_DN_USER=root
2.修改start-yarn.sh和stop-yarn.sh
cd /home/hadoop/sbin vim start-yarn.sh vim stop-yarn.sh
#HADOOP_SECURE_DN_USER=root HDFS_DatanODE_SECURE_USER=root
YARN_NODEMANAGER_USER=root YARN_RESOURCEMANAGER_USER=root
3.同步到其它机
cd /home/hadoop/sbin scp * c2:/home/hadoop/sbin scp * c3:/home/hadoop/sbin scp * c4:/home/hadoop/sbin
