解决方案：

在/hadoop/sbin路径下查找start-dfs.sh和stop-dfs.sh两个文件，在其顶部都添加上

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

顺便在start-yarn.sh和stop-yarn.sh两个文件顶部也分别加上

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