start-dfs.sh出错

ERROR: Attempting to operate on hdfs namenode as root
ERROR: but there is no HDFS_NAMENODE_USER defined. Aborting operation.
Starting datanodes
ERROR: Attempting to operate on hdfs datanode as root
ERROR: but there is no HDFS_DATANODE_USER defined. Aborting operation.
Starting secondary namenodes [iz2ze49dsj767ouqcmxlqaz]
ERROR: Attempting to operate on hdfs secondarynamenode as root
ERROR: but there is no HDFS_SECONDARYNAMENODE_USER defined. Aborting operation.

(缺少用户定义而造成的)因此编辑启动和关闭

$ vim sbin/start-dfs.sh 
$ vim sbin/stop-dfs.sh

顶部空白处

HDFS_DATANODE_USER=root
HADOOP_SECURE_DN_USER=hdfs
HDFS_NAMENODE_USER=root
HDFS_SECONDARYNAMENODE_USER=root

start-yarn.sh出错

Starting resourcemanager ERROR: Attempting to operate on yarn resourcemanager as root ERROR: but there is no YARN_RESOURCEMANAGER_USER defined. Aborting operation. Starting nodemanagers ERROR: Attempting to operate on yarn nodemanager as root ERROR: but there is no YARN_NODEMANAGER_USER defined. Aborting operation.

是因为缺少用户定义造成的,所以分别编辑开始和关闭脚本

$ vim sbin/start-yarn.sh 
$ vim sbin/stop-yarn.sh 

顶部添加

YARN_RESOURCEMANAGER_USER=root
HADOOP_SECURE_DN_USER=yarn
YARN_NODEMANAGER_USER=root
