hadoop - Hadoop:resourcemanager不在本地主机上运行

Question

所以我无法在 hadoop 3.1.1 上访问http:// localhost:8088 /
这是我所做的:

bin/hdfs namenode -format

sbin/start-dfs.sh

bin/hdfs dfs -mkdir /user

bin/hdfs dfs -mkdir /user/username

NameNode的Web界面有效，但Resource Manager的Web界面无效。

export HADOOP_OPTS=-Djava.library.path=$HADOOP_HOME/lib
    
export PATH=$HADOOP_HOME/bin:$PATH
    
export PATH=$HADOOP_HOME/sbin:$PATH

问题是当我运行时: sbin / start-yarn.sh 这是结果
在[]上启动资源管理器
启动节点管理器

它不应该说:在[localhost]上启动resourcemanagers吗？

Answer 1

默认情况下，文档中主机名的默认值为0.0.0.0，而不是localhost，如果要在下面显式配置属性，请在此处提供其默认值，并覆盖它们。

yarn.resourcemanager.hostname 0.0.0.0 The hostname of the RM. yarn.resourcemanager.address ${yarn.resourcemanager.hostname}:8032 The address of the applications manager interface in the RM.
