hadoop配置-配置伪分布无法启动ResourceManager

通过jps查看没有启动ResourceManager, 按照下面的路径查看日志

usr/local/Cellar/hadoop/3.2.1/libexec/logs/xxxresourcemanagerxxx.log 通过vscode打开

网上查一下, 是jdk版本导致, 我是用的jdk11, 说是jdk9之后就要怎么怎么处理.
网上给的通过修改hadoop-env.sh的方式,写--allxxx这种方式我试了也不成功,所以直接还是安装jdk8就好了. (安装参考:mac实现不同版本jdk切换)

由于上面方式可以实现不同jdk切换, 但是还是会自动跳转到jdk11, 所以还是要修改hadoop-env.sh, 使用指定版本的jdk
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_261.jdk/Contents/Home

配置文件的位置如下
