解决方案一:

输入如下命令,在环境变量中添加下面的配置

vi /etc/profile

然后向里面加入如下的内容

export HDFS_NAMENODE_USER=root
export HDFS_DATANODE_USER=root
export HDFS_SECONDARYNAMENODE_USER=root
export YARN_RESOURCEMANAGER_USER=root
export YARN_NODEMANAGER_USER=root

输入如下命令使改动生效

source /etc/profile

 解决方案二:

将start-dfs.sh,stop-dfs.sh(在hadoop安装目录的sbin里)两个文件顶部添加以下参数

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

将start-yarn.sh,stop-yarn.sh(在hadoop安装目录的sbin里)两个文件顶部添加以下参数

YARN_RESOURCEMANAGER_USER=root
HADOOP_SECURE_DN_USER=yarn
YARN_NODEMANAGER_USER=root
