问题：

Hadoop组件未启动

廉宇
2023-03-14

我是hadoop的新手，我已经学习了micheal install（http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/）。

当我运行命令/usr/local/hadoop/bin/start-all.sh时，通常这将启动计算机上的Namenode、Datanode、Jobtracker和Tasktracker。

我得到的只有TaskTracker从这里开始的是跟踪：

请确保您已经创建了目录/app/hadoop/tmp/dfs/namesecondary并具有适当的权限。此外，检查日志（NN,DN,SNN,JT）也会有帮助。如果您仍然面临这个问题，请将日志和配置文件一起显示给我们。

针对您的评论：

InconsistentFSStateException：目录/app/hadoop/tmp/dfs/name处于不一致状态：存储目录不存在或不可访问。
