我正在通过 VMware 在 ubuntu 14.04 上设置 Hadoop-2.7.2。
按照 michael g. noll 的教程中描述的步骤，当我尝试这样做时，
/usr/local/hadoop/sbin/start-all.sh
我得到了这个东西，
Instead use start-dfs.sh and start-yarn.sh

当我执行 stop-all.sh 时，它给出了同样的错误
我尝试通过安装 execstack 并运行命令来修复它
execstack -c /usr/local/hadoop/lib/native/lib-hadoop.so.1.0.
这个内容传达了同样的信息，

除此之外，我可以连接到我的 namenode Web UI，但无法连接到 Jobtracker 和 Tasktracker。
这可能是 Linux 错误。不知道如何解决。
答案1
编辑主机文件
sudo nano /etc/hosts
查看您的设备名称是否与 hosts 文件中的设备名称匹配
例如 kingpc 是与 hosts 文件中的名称匹配的设备名称
