我试图启动Hadoop
./sbin/start-dfs.sh
但是我收到以下错误
Starting namenodes on [localhost]
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.
我在执行start
之前从终端运行了这个export HADOOP_USER_NAME="myname"
export HDFS_NAMENODE_USER="myname"
export HDFS_DATANODE_USER="myname"
export HDFS_SECONDARYNAMENODE_USER="myname"
export YARN_RESOURCEMANAGER_USER="myname"
export YARN_NODEMANAGER_USER="myname"
我还创建了数据文件夹并将其分配给同一个用户组。我还缺少什么？
