提供两种解决方法，一是直接修改start-dfs.sh、stop-dfs.sh、start-yarn.sh和stop-yarn.sh脚本，二是更推荐的方式，编辑hadoop-env.sh文件，定义用户变量，确保所有组件启. 当您遇到“ERROR: but there is no HDFS_NAMENODE_USER defined. Aborting operation.”这样的错误时，意味着系统无法找到已定义的HDFS_NAMENODE_USER环境变. 在执行官方文档安装指南的时候，输入命令 sbin/start-dfs.sh 报错出现 there is no HDFS_NAMENODE_USER defined.

in hadoop config's hadoop-env.sh specified HDFS_NAMENODE_USER and HDFS_DATANODE_USER user is something else. Hence we need to correct and make it. ERROR: but there is no YARN_NODEMANAGER_USER defined. Aborting operation. 解决方法： 在Hadoop安装目录下找到sbin文件夹. 在里面修改四个文件. 1、对于 start-dfs.sh 和 stop. 本文解决了Hadoop集群启动时因缺失用户配置和JAVA_HOME环境变量导致的错误，通过修改配置文件并设置JAVA_HOME，成功启动集群。
