Attempting to operate on hdfs namenode as root

在/hadoop/sbin路径下：
将start-dfs.sh，stop-dfs.sh两个文件顶部添加以下参数

#!/usr/bin/env bash
HDFS_DATANODE_USER=root
HADOOP_SECURE_DN_USER=hdfs
HDFS_NAMENODE_USER=root
HDFS_SECONDARYNAMENODE_USER=root

还有，start-yarn.sh，stop-yarn.sh顶部也需添加以下：

#!/usr/bin/env bash
YARN_RESOURCEMANAGER_USER=root
HADOOP_SECURE_DN_USER=yarn
YARN_NODEMANAGER_USER=root


# Licensed to the Apache Software Foundation (ASF) under one or more

修改后重启 ./start-dfs.sh，成功！
