Hadoop Nodemanager因错误而失败无法获取组信息

Question

我已安装kerberos配置的Apache hadoop（2.8.5）。 NameNode，DataNode和ResourceManager运行正常，但Nodemanager无法启动并出现错误：

Can't get group information for hadoop#configured value of yarn.nodemanager.linux-container-executor.group - Success.

文件权限：

container-executor.cfg: -rw------- 1 root hadoop
container-executor: ---Sr-s--- 1 root hadoop

container-executor.cfg

yarn.nodemanager.local-dirs=/hadoop/data/yarn/local
yarn.nodemanager.linux-container-executor.group=hadoop#configured value 
of yarn.nodemanager.linux-container-executor.group
banned.users=hdfs,yarn,mapred,bin,root#comma separated list of users who can not run applications
min.user.id=1000#Prevent other super-users

Answer 1

只需删除评论：

  

#configured值

从配置行：

  

yarn.nodemanager.linux-container-executor.group

在 container-executor.cfg 文件中

它看起来应该像这样：

yarn.nodemanager.local-dirs=/hadoop/data/yarn/local
yarn.nodemanager.linux-container-executor.group=hadoop
of yarn.nodemanager.linux-container-executor.group
banned.users=hdfs,yarn,mapred,bin,root
min.user.id=1000

此配置文件在空格，注释等方面存在历史问题。
