這篇文章主要介紹了解決hadoop啟動(dòng)報(bào)錯(cuò)ERROR: Attempting to operate on hdfs namenode as root的方法,hadoop-3.1.0啟動(dòng)hadoop集群時(shí)還有可能可能會(huì)報(bào)如下錯(cuò)誤,需要的朋友可以參考下

hadoop-3.1.0啟動(dòng)hadoop集群時(shí)還有可能可能會(huì)報(bào)如下錯(cuò)誤:

[root@localhost sbin]# start-all.sh
Starting namenodes on [hadoop]
ERROR: Attempting to operate on hdfs namenode as root
ERROR: but there is no HDFS_NAMENODE_USER defined. Aborting operation.
Starting datanodes

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

解決方案一：

輸入如下命令，在環(huán)境變量中添加下面的配置

vi /etc/profile

然后向里面加入如下的內(nèi)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

輸入如下命令使改動(dòng)生效

source /etc/profile

解決方案二：

將start-dfs.sh，stop-dfs.sh(在hadoop安裝目錄的sbin里)兩個(gè)文件頂部添加以下參數(shù)

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

將start-yarn.sh，stop-yarn.sh(在hadoop安裝目錄的sbin里)兩個(gè)文件頂部添加以下參數(shù)

YARN_RESOURCEMANAGER_USER=root
HADOOP_SECURE_DN_USER=yarn
YARN_NODEMANAGER_USER=root
